- There's still a bug in the new timer code. If you think you hit it,
please revert
timers-fixes-improvements-fix.patch then
timers-fixes-improvements-smp_processor_id-fix.patch then
timers-fixes-improvements.patch
or, better, fix the bug.
FWIW, I can reproduce this timer bug fairly consistently, by simply
rebooting my cisco router. That means that my linux box has no default
gateway, and hence the networking blows up within about 30s and dies
with a stack trace which has references to timers.
I'll back out those three patches and see if it continues, but hopefully
my little discovery is useful to someone in terms of coming up with a
fix....
Rather than backing things out, please add this instead:

The bug was identified by Maneesh Soni.
Yup, this patch seems to fix it. I did 3 router reboots, and my linux
box held up fine. Previous to this patch it had fatally oopsed 5 out of
the 6 times I reloaded the router..
Thanks :)
