thinkpad_acpi: unhandled HKEY event 0x6040

My Thinkpad w520 crashes moments after I unplug it from AC power.  It
didn't crash when I was using the integrated video, but now I'm using
the Quadro 1000M (I have the display set to "discrete ..." in the
bios).  I'm running 64 bit Ubuntu 11.04 with the binary nVidia driver
version 270.41.19.  Right before it crashes, I see this in the syslog:

May 30 18:12:17 monolith init: anacron main process (829) killed by TERM signal
May 30 18:12:17 monolith kernel: [ 1382.440289] thinkpad_acpi: THERMAL
ALERT: unknown thermal alarm received
May 30 18:12:17 monolith kernel: [ 1382.440302] thinkpad_acpi:
unhandled HKEY event 0x6040
May 30 18:12:17 monolith kernel: [ 1382.440309] thinkpad_acpi: please

ibm-acpi-devel@...
May 30 18:12:17 monolith kernel: [ 1382.441274] thinkpad_acpi: EC

If you would like more info, let me know.

Thanks,
Peter

OK, this appears to occur exactly when I press the Fn key. I need to
press the Fn key when I switch to a VT to see the Oops message, and
that is why it is always appears when I see a kernel Oops. It appears
to be harmless in and of it self.

I don't know of any machines but Thinkpad providing such a LED
control, so I'm fine with any naming basically :)  Though, if there
are many of such mute LEDs, any parseable form like laptop::xxx-mute
would be better for future?

Re: (Thinkpad T400s) thinkpad_acpi: unhandled HKEY event 0x6000

Thank you for your report, and apologies for the time it took for me to
answer back.  The newest version of the driver will remove this message,
the event just means you pressed the NumLock key.

John,

Thank you for your report.

Just to make sure I did understand it right:  if you press the Fn key
*alone*, with no other keys, your thinkpad issues event 0x6005.  Is that
correct?

Also, when you press Fn+<some other key>, does it issue event 0x6005 at all?

Does it issue the event when you press the key, when you release the key, or
both?

Please.  It is the first time I heard of this event...  Here are some
questions, to help track it down:

1. Did you ever get that event while the Quadro was *disabled* in BIOS?

2. Do you get that event when you switch to BATTERY only?  Or do you get
   it also when you switch back to AC ? Maybe you could test it in single
   user text mode, as that might help avoid the crash...

Thanks in advance for any help you can give so that we can track down

Re: T520 crashing

Event 0x6000 just means you pressed numlock, so it should be unrelated to
the crash...

I will have to ask Lenovo to add a dmi string with version info on the new
thinkpads (it can be a new one that doesn't have IBM in the name, as long as
it is in there...).

That could take a while (if they accept my request at all).

thinkpad-acpi release 0.24-20110604 uploaded to ibm-acpi.sf.net

I have released version 0.24-20110604 of thinkpad-acpi through the
sourceforge.net release system.

Patches are available for 2.6.32, 2.6.35, 2.6.38 and 2.6.39, at:
https://sourceforge.net/projects/ibm-acpi/files/thinkpad-acpi/0.24-20110604/

Support for 2.6.33-longterm and 2.6.34-longterm kernels will only be
provided if there are enough requests or someone provides a very convincing
reason.

Support for all other kernels is discontinued, but if you'd like to adopt
the backport for one of those kernels yourself, I will help you with that.

2.6.27 might still get *minor* updates, but only if someone asks me directly
for it and it is something easy to backport.

git users can get it directly from tags or the release/* branches at:
git://repo.or.cz/linux-2.6/linux-acpi-2.6/ibm-acpi-2.6.git

Alternatively, you can also get thinkpad-acpi releases from the sf.net
secondary (backup) repository, which only contains the release/* branches
and tags:
git://ibm-acpi.git.sourceforge.net/gitroot/ibm-acpi/ibm-acpi

Users with recent Lenovo thinkpads will have a less annoying thinkpad-acpi
experience with this new version.

Note that the 2.6.32, 2.6.35 and 2.6.38 branches have a lot more changes
(backported from mainline/3.0-rc1) than just the two commits listed below.

Hmm, yet another new event (0x6050).  I would appreciate if you could help
me track down what it means...

As for your brightness change issues: try unloading the ACPI "video" module.
Does that help avoid the crashes?  If it doesn't, try unloading BOTH ACPI
"video" and "thinkpad-acpi".

If you use xrandr to change screen brightness directly (without the
hotkeys), does it cause the crash?

It is likely something nasty in KMS or X.org backlight handling.  But do
check whether a BIOS update is available for your ThinkPad, it just might
help...
