Kernel Bug Tracker – Bug 9789
Deadlock on _any_ ACPI event
Last modified: 2008-01-24 13:23:53 UTC
Latest working kernel version: 2.6.23 for sure (but I had some 2.6.24 kernel wroking)
Earliest failing kernel version: current 2.6.24, up to a7da60f41551abb3c520b03d42ec05dd7decfc7f mainline commit
Hardware Environment: x86_64
It's impossible to use any last kernel with ACPI compiled in: _any_ ACPI even hangs my laptop without any [net]console output or so.
Any ACPI even mean: lid closing, AC adapter removing/plugging in, button press.
Guess, needless to say that it's impossible to use laptop without ACPI:
no battery info, no automating AC adapter events, no hibernate on the button press.
Steps to reproduce:
It can be reproduced easily and almost 100%. I'm just booting ACPI kernel and removing AC adapter - laptop is locked.
I'm trying 2.6.24-rc5 and lower now to try to find out the problem release.
But I can boot 2.6.23 anytime - and there is no the problem there.
