Subject: BUG during shutdown - bisected to commit e2912009
Date: Fri, 1 Jan 2010 19:27:38 -0500 [thread overview]
Message-ID: <6041d2001001011627o5c494df4v37c0c466df3d444c@mail.gmail.com> (raw)
I'm getting a BUG with current kernels from
kernel/time/clockevents.c:263 when halting the system - a restart
behaves normally. I don't have a good camera handy at the moment to
capture the call stack on screen, but the call sequence is:
clockevents_notify
hrtimer_cpu_notify
notifier_call_chain
raw_notifier_call_chain
_cpu_down
disable_nonboot_cpus
kernel_power_off
sys_reboot
I bisected it down to commit e2912009: sched: Ensure set_task_cpu() is
never called on blocked tasks. There were a few commits tested along
the way where I got a freeze (with the power still on) instead of a
BUG. Reverting that commit from the current kernel doesn't look
trivial, but the commit immediately preceding this one does halt fine.
Marc
