    SubjectRe: 2.6.32.21 - uptime related crashes?
    From
    Date

    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,
