Hmm.. I just got a run_timer_softirq oops on my own laptop, slightly
different. That was not during shutdown, although there was a "yum
upgrade" finishing when that happened, so it's quite likely that there
was a service shutdown (and then restart).
I think it's related. But my oops has almost no information: the IP
that was jumped to was bogus, and the callchain is just CPU idle
followed by the softirq -> run_timers_softirq handling, so there's no
real way to see *what* triggered it.
The bad rip was ffffffffa051e250, which is not a valid code address.
It *might* be a module address, though. So this might be triggered by
rmmod on some module that doesn't remove all its timers...
Ideas?
Linus
