Hello,
On my Thinkpad T21 executing:
# echo 7 blink > /proc/acpi/ibm/led
on kernel afa26be86b65a7183ceac29bdf1f51d6fc6932f0 (few comits after
rc1) results in following oops:

I haven't seen any relevant changes in drivers/misc/thinkpad_acpi.c up
to 3de2403e6659d71b36ec820dc9b942762ddfe6eb, so I guess it's unfixed
in newer kernels.
(Please keep Cc to me.)
Thanks.

The machine was clean after a boot, correct? (no sleeps or other

Assuming the comments on the LED code from the first ibm-acpi maintainer

ibm-acpi codepath. That codepath is indeed NOT tested often, as I don't
have a way to do so. Bugs there wouldn't surprise me too much.
If you try it using the sysfs led class, do you get the same OOPS? (I
expect you to. If you don't, I *need* to know this).
Is it always a problem with the last led (number 7), or other leds also
cause the OOPS?
Also, please try the patch below, and send me the debug output it will
generate.

Yes, that's after clean boot.

Well, I try to "test" that... actually I try to use it, and see if it
breaks horribly. ;-)
It's regression from 2.6.25.

Yes, I get oops in the same place, call stack is different of course.

Leds 1-6 are ok, i.e. they do change state (on/off) and don't cause
ill effects.
Writing anything (on/off/blink) to led 7 (procfs) or "tpacpi::standby"
(sysfs) causes an reproductible oops.
> Also, please try the patch below, and send me the debug output it will
> generate.
Hmm, I added following to my .config and recompiled kernel with your patch:
+CONFIG_HAVE_UNSTABLE_SCHED_CLOCK=y # this was automatically added
+CONFIG_DEBUG_BUGVERBOSE=y
+CONFIG_DEBUG_INFO=y
+CONFIG_FRAME_POINTER=y
The result is:
thinkpad_acpi: debug: led 7, status 1, mode 2
thinkpad_acpi: debug: led is now 0x80
thinkpad_acpi: debug: will write A=0x0, B=0x80
Yes, no oops... writing on/off/blink all works through procfs and
sysfs interface works too.
Without .config changes:
thinkpad_acpi: debug: led 7, status 1, mode 2
thinkpad_acpi: debug: led is now 0x80
thinkpad_acpi: debug: will write A=0x0, B=0x80
No oops here either. Reverting this patch gives:
