Subject: system reboot after reading /proc/acpi/battery/../state

Hi,
I have a regression to report: my notebook (HP Compaq nx7000) reboots
after reading /proc/acpi/battery/C11F/state. It's pseudo -
reproduceable, occurs around every second access.

please contact me for further information (and what information would be
needed to fix this bug), I will try to compile older kernel versions to
find the corresponding acpi update this annoying bug (but it happens
for at least one month by now).

//Andreas

Unloading the watchdog driver (the TCO driver) will help you.

Thanks,

Add printks to see where it reboots... it may be faster than binary
searching acpi updates.

seems like disabling tco watchdog took care of this problem..

thanks,
