BUG: linux-2.6.26-rc1 oops at thinkpad_acpi:led_set_status

From: Karol Lewandowski
Date: Thu May 08 2008 - 19:12:56 EST


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.
