2.6.0-test4 - lost ACPI

Hi,

I am using ACPI for few years now. As far as I can see, on my machine it is only usfeul for binding events to Power button (like running fbdump) and for powering off. I'm also experimenting with swsusp, which I run by /proc/acpi/sleep.

2.6.0-test4 has a surprise for me:

Linux version 2.6.0-test4 (zdzichu@mother) (gcc version 3.3.1) #15 Sat Aug 23 12:03:

ACPI disabled because your bios is from 00 and too old ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
You can enable it with acpi=force

WTF? My BIOS was perfectly good all those years! And no, there is no upgrade for my motherboard available. Using acpi=force is ugly and un-understandable.

There are also some strange directories in /proc :

dr-xr-xr-x    2 root     root            0 Aug 23 12:50 /proc/ac_adapter/
dr-xr-xr-x    2 root     root            0 Aug 23 12:50 /proc/fan

they are empty, but they should be in /proc/acpi/

Attached files:
Output from dmidecode, lspci -v, my dmesg and /proc/cpuinfo

[Please CC me on replies. Thank you].

me too.

One of my trusty-but-old testboxes does exactly the same thing. It's just the ACPI guys running away from broken BIOSes I think ;)

Add "acpi=force" to your kernel boot command line and everything should work as before.

It does not work. It halts in beetween ps/2 mouse init and serio init. Adding "acpi=force pci=noacpi" solves that.

OK. Please send a full report to [email protected]. Here is Len's how-to-report-ACPI problems recipe:

Regarding how to field these in general...
Bugzilla would be really helpful, because we've got multiple bugs and multiple people working on them and bugzilla is better than e-mail at keeping the relevant bits together. bugzilla with component=ACPI and owner [email protected] or [email protected] should do the trick.

The dmesg output of the failing case is really helpful,
As is the output of acpidmp to examine the ACPI tables on the system. (Red Hat includes both of these in their severn beta1, acpidmp is also in pmtools on intel's ACPI web page)
dmidecode output is useful to identify the BIOS version.

Of course the 1st thing to check with ACPI failures is that the BIOS version shown by dmidmp is the latest provided by the vendor... Plus, if we determine the BIOS is toast, DMI provides what we need to add the system to the DMI or acpi blacklists.

We're seeting the most problems on VIA chip-sets with no IO-APIC. The one below is unusual because it is a 2-way system with 3 IO-APICs.

The latest code in linus' tree includes ACPICA 20030813, which is slightly newer than the one below, it might be a good idea to try that with CONFIG_ACPI_DEBUG. Note that it will spit out the DMI info upon the mount root failure automatically.

I don't recall seeing the ACPI disabled line, but mine had the same problem halting between PS/2 init and serio. The change I noticed was that IRQ's were being allocated differently, and that is what I attributed this failure to. My motherboard worked with 2.6.0-test3-mm2, but has not worked since 2.6.0-test3-mm3 (when the new ACPI code was added).

I'll have to try this acpi=force and pci=noacpi, otherwise I have to disable USB and sound to get it to boot.
