Hi Len and Rafael,

With 3.7-rc3, I'm seeing a constant stream of these errors in the kernel log for my MacBook Pro:

[30443.430133] ACPI: EC: input buffer is not empty, aborting transaction
[30443.430145] ACPI Exception: AE_TIME, Returned by Handler for [EmbeddedControl] (20120913/evregion-501)

[30443.430202] ACPI Exception: AE_TIME, Evaluating _BST (20120913/battery-464)

They never showed up before in 3.7-rc2.

Anything I should try out to resolve this?

thanks,

Well, there are the following two post-3.6 EC-related commits:

commit 67bfa9b60bd689601554526d144b21d529f78a09

Author: Feng Tang <[email protected]>
Date:   Fri Sep 28 15:22:01 2012 +0800

ACPI: EC: Add a quirk for CLEVO M720T/M730T laptop

commit a520d52e99b14ba7db135e916348f12f2a6e09be

Author: Feng Tang <[email protected]>
Date:   Fri Sep 28 15:22:00 2012 +0800

ACPI: EC: Make the GPE storm threshold a module parameter

Can you please check if reverting the second one helps?

ACPI: EC: Make the GPE storm threshold a module parameter
Can you please check if reverting the second one helps?

That last one seems like it would be it, if the module parameter got changed. And now I can't duplicate it at all, 3.7-rc3 works fine. Ick, sorry for the noise, I don't know what happened. If I see the above errors again, I'll let you know, and I'll also check the ec module parameter first to ensure it didn't change from the default of 8.

thanks,

While there is no process that load CPU up to 100% or like that. I think that this because of processes that is done in kernel space. (basically that one who write such errors)

Ah, ok, that means it's not something new in 3.7-rc, so maybe it's just never worked properly for this hardware :)

So it's not a regression, just an ACPI issue, any ACPI developer have an idea about this?

When this messages appears, I was running from AC, not from battery.

Can you please send the output of acpidump from the affected machine(s)?

What am I doing wrong here?

Is there a newer version of pmtools than the one labled pmtools-20071116 that I should be using? A link to download it would be appreciated.

I doubt this problem is sometimes inevitable for some machines, because AFAIK most modern machines have the race problem for EC HW controller, as both OS side and the BIOS may access the EC HW at the same time without any race control.

For this case, usually the battery and thermal modules (which may be controlled through EC) are always monitored by BIOS, when OS also frequently visit them too, the EC's own state machine may be broken and not responsive due to the race, then cause the timeout error. And how severe the problem will be depends on the EC HW, the quality of BIOS code and OS/driver code.

Myself have seen the similar "ACPI: EC: input buffer is not empty, aborting transaction" error message on one laptop when its EC is busy visited by OS.

btw, in EC driver I see a "ec->global_lock", don't know if it was designed to control the race between OS and BIOS.

Thanks,
Feng

Thanks for the info.

And per my check, most of ACPI FW don't implement this lock, say after driver probe, the ec->global_lock will be 0.

I doubt this problem is sometimes inevitable for some machines, because AFAIK most modern machines have the race problem for EC HW controller, as both OS side and the BIOS may access the EC HW at the same time without any race control.
For this case, usually the battery and thermal modules (which may be controlled through EC) are always monitored by BIOS, when OS also frequently visit them too, the EC's own state machine may be broken and not responsive due to the race, then cause the timeout error. And how severe the problem will be depends on the EC HW, the quality of BIOS code and OS/driver code.
Myself have seen the similar "ACPI: EC: input buffer is not empty, aborting transaction" error message on one laptop when its EC is busy visited by OS.
btw, in EC driver I see a "ec->global_lock", don't know if it was designed to control the race between OS and BIOS.

Actually, it is not the address of the global lock, the FACS contains the actual global lock:

From acpi5.0 spec:

ROM BIOS. The Global Lock is a 32-bit (DWORD) value in read/write memory located within the FACS and is accessed and updated by both the OS environment and the SMI environment in a defined manner to provide an exclusive lock. Note: this is not a pointer to the Global Lock, it is the actual memory location of the lock. The FACS and Global Lock may be located anywhere in physical memory.

I have such message again, and load avg up to 30, and the increase up to 40, after to 50.

I found this https://bugzilla.kernel.org/show_bug.cgi?id=14733
and I after I compile kernel with this patch write message about results.

Also I want to note that after I suspend laptop to ~20-15 minutes and resume, it works fine.
And no such spam in log.

But after this hack if open lid, laptop not exit from suspend mode, for exit from it, I must manually press key on keyboard. I try to restart acpid, laptop-mode but nothing of this helped me.

Actually, it is not the address of the global lock, the FACS contains the actual global lock:
From acpi5.0 spec:
ROM BIOS. The Global Lock is a 32-bit (DWORD) value in read/write memory located within the FACS and is accessed and updated by both the OS environment and the SMI environment in a defined manner to provide an exclusive lock. Note: this is not a pointer to the Global Lock, it is the actual memory location of the lock. The FACS and Global Lock may be located anywhere in physical memory.

Robert,
You say that FACS table contains the address of the global lock. But in my case https://gist.github.com/4037687 it seems to be empty, so this means that my laptop don't have global lock?

The DSDT is supposed to define the _GLK control method on the EC if the BIOS needs to perform its own access which may conflict with the OS usage. If it doesn't, then it should be the case that either the BIOS doesn't touch the EC itself or it uses a separate interface that doesn't cause conflicts with what the OS is doing.

The ACPI Global Lock is in fact intended to provide exclusion between the BIOS and the OS.

Thanks for the info.
And per my check, most of ACPI FW don't implement this lock, say after driver probe, the ec->global_lock will be 0.
Quoted 125 lines
The DSDT is supposed to define the _GLK control method on the EC if the BIOS needs to perform its own access which may conflict with the OS usage. If it doesn't, then it should be the case that either the BIOS doesn't touch the EC itself or it uses a separate interface that doesn't cause conflicts with what the OS is doing.

So it's not a regression, just an ACPI issue, any ACPI developer have an idea about this?
Can you please send the output of acpidump from the affected machine(s)?
I doubt this problem is sometimes inevitable for some machines, because AFAIK most modern machines have the race problem for EC HW controller, as
both OS side and the BIOS may access the EC HW at the same time without any race control.
For this case, usually the battery and thermal modules (which may be controlled through EC) are always monitored by BIOS, when OS also frequently visit them too, the EC's own state machine may be broken and not responsive due to the race, then cause the timeout error. And how severe the problem will be depends on the EC HW, the quality of BIOS code and OS/driver code.
Myself have seen the similar "ACPI: EC: input buffer is not empty, aborting transaction" error message on one laptop when its EC is busy visited by OS.
Quoted 6 lines
Quoted 6 lines
btw, in EC driver I see a "ec->global_lock", don't know if it was designed
to control the race between OS and BIOS.
Thanks,
Feng

What am I doing wrong here?
Is there a newer version of pmtools than the one labled pmtools-20071116 that I should be using? A link to download it would be appreciated.

I'd like to ask what happened to this issue, because I'm seeing similar messages on latest 3.8-rc4 as well, and I cannot read the battery info anymore once this happens and the laptop does not suspend to RAM anymore -- it suspends fine before these messages.

The laptop is a Macbook Pro with retina display and I'm using the develpoment version of openSUSE 12.3 updated as of yesterday.

Here is the output from dmesg:

Well, I can't really say at the moment.

Please file a bug at bugzilla.kernel.org against ACPI and assign it to Lv Zheng.

Please put all of the information you've collected so far in there and add the output of acpidump as an attachment.

Thanks,

Carlos, did you try this patch?
https://bugzilla.kernel.org/attachment.cgi?id=73510

I started to test it now and I will try to have an uptime of more than 7 days in order to have a veridict.

[ The problem is that I started to encounter a dvb-related issue
which requires me to reboot after trying to watch tv, so let's wee what happens. ]

I'm seeing this again right now. I'm wondering if it's because I'm running on battery power at the moment:

ec_storm_threshold is still set to 8 in /sys/module/acpi/parameters/ so that's not the issue here.

And also loadavg is too high ~ 10
While there is no process that load CPU up to 100% or like that. I think that this because of processes that is done in kernel space. (basically that one who write such errors)

Ah, ok, that means it's not something new in 3.7-rc, so maybe it's just never worked properly for this hardware :)
So it's not a regression, just an ACPI issue, any ACPI developer have an idea about this?
Can you please send the output of acpidump from the affected machine(s)?
Quoted 7 lines
# ./acpidump
ACPI tables were not found. If you know location of RSD PTR table (from dmesg, etc), supply it with either --addr or -a option
What am I doing wrong here?
Is there a newer version of pmtools than the one labled pmtools-20071116 that I should be using? A link to download it would be appreciated.
I'd like to ask what happened to this issue, because I'm seeing similar messages on latest 3.8-rc4 as well, and I cannot read the battery info anymore once this happens and the laptop does not suspend to RAM anymore -- it suspends fine before these messages.
The laptop is a Macbook Pro with retina display and I'm using the develpoment version of openSUSE 12.3 updated as of yesterday.
Here is the output from dmesg:

Anyone has more information about this?
Is acpidump still not working?
It works for me, I've uploaded it to
http://www.damtp.cam.ac.uk/user/crm66/acpidump-rmbp.txt
And my 'dmesg' from a freshly-booted 3.8-rc5 is here

What's under /sys/firmware/acpi/tables/ ?
[mafra@linux-ahr8:~]$ ls /sys/firmware/acpi/tables/

DMAR  dynamic/  FACP  HPET  SBST  SSDT10  SSDT12  SSDT3  SSDT5  SSDT7  SSDT9
I should say that sometimes it takes +3 days for this problem to appear, with many successful s2ram in between, sometimes it takes less than 1 day. I could not figure out a pattern.
Any other info I can provide?
