gericom notebook reboots instead of poweroff

Hi,

I have a Gericom 1st supersonic (PIII 1.2Ghz) laptop, running Debian
Sarge (up-to-date). I have it since ~2.4.14, and until 2.6.8.1 the
'halt' command shut down the machine correctly. Starting with 2.6.8.1-bk1
it reboots. :( I realize that -bk1 has a big ACPI update, which may be
the problem IMHO.
I have tried to look into existing bugreports, but could not find any
similar to this on the Kernel Bugzilla nor in the ACPI Bugzilla. All I
could found some note that Local APIC can cause problems, but even if I
disable that, the problem remains. Asked LKML without any reply; hope
here I can get some help, so if you need more information about it,
please let me know.
Some maybe relevant bits from the machine:

Anyone have at least a shot what can cause this problem? I would be happy to try out patches or back out ones from -bk1 if needed.

Any help is greatly appreciated in advance,

Hi,

the same problem is with my ACER 632 too.

I've tried disable wakeup devices /proc/acpi/wakeup, but with no success.

Hi!

What happens with acpi=off?

I have evo n620c here which has similar symptoms, and has another funny set of symptoms with acpi=off...

I have exactly the same problem with my ACER TM 636. Will try with acpi=off asap and report.

Do you also have funny thermal and battery readings when running on batteries?

Hi!

Thermal seems to more or less work until I do swsusp; battery reading seems to be okay. evo is really different beast from acer...

Hi,

No offence taken; I was looking into the Bugzilla, as well to the mail
archives. Could not find anything relevant that time. But as I have reported this, other people showed up, and followed on my bugreport here on this mailing list and on the kernel bugzilla, as well you opened up SuSE bugzilla later on. I think you missed my _original_ mail.
Anyway it is a bit bad that developers haven't show up. As noted, I
could sharpen the location of this bug to 2.6.8.1 and the later added 2.6.9-bk1; still could not find out how to get -bk1 into changeset pieces and apply those step by step while recompiling the kernel, reboot and see in which changeset this bug was introduced. Blame me, this is all what I can offer to help fixing this.
I would greatly appreciate any help how to handle BitKeeper to get those changesets individualy.

Kind regards,
Laszlo

Hi!

Ah, sorry, I was replying on old mails...

It should be possible to download individual patches from bkbits.net, but it is likely to be pretty tedious process.....

It is. :( I have already tried that approach (from
http://linux-acpi.bkbits.net:8080/26-stable-release/tags?nav=index.html ), but simply clicking on 'later CSets' in the v2.6.8.1 line does not work for two fold: 1) you can't be sure that ACPI changes are synced on each release, so some 2.6.9-bk1 ACPI changes may come from older times and 2) not all CSets accepted by Andrew/Linus, they are selective. But thanks for your BK/ChangeLog proposal, that detailed changelog you described would help a lot.

Thanks,
Laszlo

[ACPI] restore PCI Interrupt Link Devices upon resume

* register as as a sys_device so that we can get resume callbacks and restore interrupt routing state.
* add acpi_pci_link_resume(), which will be called when resuming from a suspend state that needs IRQ routing to be restored. This fixes issues reported on the mailing lists, e.g.:
http://marc.theaimsgroup.com/?l=acpi4linux&m=109142999328643&w=2
* rename setonboot --> initialized
* change to test acpi_noirq in init

We want to initialize everything on S3 resume in case the BIOS points an interrupt link somewhere we didn't expect. (Doing so avoids "missing interrupt" or "irq x: nobody cared" problems.) According to Len, past experience has shown that it's a good idea to initialize only devices that exist or were explicitly asked for, so we try to initialize only the IRQ's that were previously initialized at some point before suspend, by checking the "initialized" flag. This corresponds to links that have PCI devices attached. Everything else, we leave alone. Assuming the BIOS does the same thing on resume that it did on boot, this will leave all the unused links in the same state that they were on boot.

We are registered as a sysdev in order to do this work fairly early during resume, before devices are resumed; some devices may not call pci_device_enable.

Previous "setonboot once" behavior is left in place, to be conservative.

[ACPI] ACPICA 20040715 from Bob Moore

Restructured the internal HW GPE interfaces to pass/track the current state of interrupts (enabled/disabled) in order to avoid possible deadlock and increase flexibility of the interfaces.

Implemented a "lexicographical compare" for String and Buffer objects within the logical operators -- LGreater, LLess, LGreaterEqual, and LLessEqual -- as per further clarification to the ACPI specification. Behavior is similar to C library "strcmp".

Completed a major reduction in CPU stack use for the acpi_get_firmware_table external function. In the 32-bit non-debug case, the stack use has been reduced from 168 bytes to 32 bytes.

Deployed a new run-time configuration flag, acpi_gbl_enable_interpeter_slack, whose purpose is to allow the AML interpreter to forgive certain bad AML constructs. Default setting is FALSE.

Implemented the first use of acpi_gbl_enable_interpeter_slack in the Field IO support code. If enabled, it allows field access to go beyond the end of a region definition if the field is within the region length rounded up to the next access width boundary (a common coding error.)

Renamed OSD_HANDLER to acpi_osd_handler, and OSD_EXECUTION_CALLBACK to acpi_osd_exec_callback for consistency with other ACPI symbols. Also, these symbols are lowercased by the latest version of the acpisrc tool.

The prototypes for the PCI interfaces in acpiosxf.h have been updated to rename "register" to simply "reg" to prevent certain compilers from complaining.

[ACPI] ACPICA 20040615 from Bob Moore

Implemented support for Buffer and String objects (as per ACPI 2.0) for the following ASL operators: LEqual, LGreater, LLess, LGreaterEqual, and LLessEqual.

[ACPI] ACPICA 20040527 from Bob Moore

Completed a new design and implementation for EBDA (Extended BIOS Data Area) support in the RSDP scan code. The original code improperly scanned for the EBDA by simply scanning from memory location 0 to 0x400. The correct method is to first obtain the EBDA pointer from within the BIOS data area, then scan 1K of memory starting at the EBDA pointer. There appear to be few if any machines that place the RSDP in the EBDA, however.
http://bugme.osdl.org/show_bug.cgi?id=2415

Integrated a fix for a possible fault during evaluation of BufferField arguments. Obsolete code that was causing the problem was removed. (Asus laptop boot crash)
https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=121760

Found and fixed a problem in the Field Support Code where data could be corrupted on a bit field read that starts on an aligned boundary but does not end on an aligned boundary. Merged the read/write "datum length" calculation code into a common procedure.

[ACPI] ACPICA 20040514 from Bob Moore

Fixed a problem where hardware GPE enable bits sometimes not set properly during and after GPE method execution. Result of ACPICA 20040427 changes.

Removed extra "clear all GPEs" when sleeping/waking.

Removed acpi_ht_enable_gpe and acpi_hw_disable_gpe, replaced by the single acpi_hw_write_gpe_enable_reg. Changed a couple of calls to the functions above to the new acpi_ev* calls as appropriate.

ACPI_OS_NAME was removed from the OS-specific headers. The default name is now "Microsoft Windows NT" for maximum compatibility. However this can be changed by modifying the acconfig.h file. Fixes EHCI probe issue:
http://bugme.osdl.org/show_bug.cgi?id=1762

Allow a single invocation of acpi_install_notify_handler for a handler that traps both types of notifies (System, Device). Use ACPI_ALL_NOTIFY flag.

Run _INI methods on ThermalZone objects. This is against the ACPI specification, but there is apparently ASL code in the field that has these _INI methods, and apparently "other" AML interpreters execute them.

Performed a full 16/32/64 bit lint that resulted in some small changes.

[ACPI] ACPICA 20040427 from Bob Moore

Completed a major overhaul of the GPE handling within ACPI CA. There are now three types of GPEs:
wake-only; runtime-only; combination wake/run.

The only GPEs allowed to be combination wake/run are for button-style devices such as a control-method power button, control-method sleep button, or a notebook lid switch. GPEs that have an _Lxx or _Exx method and are not referenced by any _PRW methods are marked for "runtime" and hardware enabled.

Any GPE that is referenced by a _PRW method is marked for "wake" (and disabled at runtime). However, at sleep time, only those GPEs that have been specifically enabled for wake via the acpi_enable_gpe() interface will actually be hardware enabled.

A new external interface has been added, acpi_set_gpe_type() that is meant to be used by device drivers to force a GPE to a particular type. It will be especially useful for the drivers for the button devices mentioned above.

Completed restructuring of the ACPI CA initialization sequence so that default operation region handlers are installed before GPEs are initialized and the _PRW methods are executed. This will prevent errors when the _PRW methods attempt to access system memory or I/O space.

GPE enable/disable no longer reads the GPE enable register. We now keep the enable info for runtime and wake separate and in the GPE_EVENT_INFO. We thus no longer depend on the hardware to maintain these bits.

Always clear the wake status and fixed/GPE status bits before sleep, even for state S5.

Improved the AML debugger output for displaying the GPE blocks and their current status.

Added new strings for the _OSI method, of the form "Windows 2001 SPx" where x = 0,1,2,3,4.

Fixed a problem where the physical address was incorrectly calculated when the Load() operator was used to directly load from an Operation Region (vs. loading from a Field object.) Also added check for minimum table length for this case.

Fix for multiple mutex acquisition. Restore original thread SyncLevel on mutex release.

Added ACPI_VALID_SXDS flag to the acpi_get_object_info interface for consistency with the other fields returned.

Shrunk the ACPI_GPE_EVENT_INFO structure by 40%. There is one such structure for each GPE in the system, so the size of this structure is important.

CPU stack requirement reduction:
Cleaned up the method execution and object evaluation paths so that now a parameter structure is passed, instead of copying the various method parameters over and over again.

In evregion.c:
Correctly exit and reenter the interpreter region if and only if dispatching an operation region request to a user-installed handler. Do not exit/reenter when dispatching to a default handler (e.g., default system memory or I/O handlers)

[ACPI] ACPICA 20040402 from Bob Moore

Fixed an interpreter problem where an indirect store through an ArgX parameter was incorrectly applying the "implicit conversion rules" during the store. From the ACPI specification: "If the target is a method local or argument (LocalX or ArgX), no conversion is performed and the result is stored directly to the target". The new behavior is to disable implicit conversion during ALL stores to an ArgX.

Changed the behavior of the _PRW method scan to ignore any and all errors returned by a given _PRW. This prevents the scan from aborting from the failure of any single _PRW.

Moved the runtime configuration parameters from the global init procedure to static variables in acglobal.h. This will allow the host to override the default values easily.

Hi Pavel,

Indeed! I have already fetched most of the ACPI changes from the BK
tree (~280kb in all). Also three way merged (the kernel source is not the same when the ACPI folks created the changeset and when it was applied by Andrew; there are even almost six months old patches!) ~220kb of the changes, tried but still looking -- Murphy works, and I bet the bug will be in the very last changeset I try. :-|
Now I must work on something else, but at last I will continue on
Tuesday.

Thank you very much,
Laszlo/GCS
