Re: 2.6.32.21 - uptime related crashes?

[MINOURA Makoto / 箕浦 真]

We're experiencing similar but slightly different
problems.  Some KVM hosts crash after 210-220 uptime.
Some of them hits divide-by-zero, but one of them shows:

[671528.8780080] BUG: soft lockup - CPU#4 stuck for 61s! [kvm:11131]

(sorry we have no full crash message including the backtrace)

The host kernel is 2.6.32.11-based (ubuntu 2.6.32-22-server,
2.6.32-22.36).

I'm not sure but probably the task scheduler is confusing by
the sched_clock overflow?

Thanks,
