[Xen-devel] BUG: soft lockup - CPU#1 stuck for 61s! [udevd:4865]

["James Harper" <james.harper@xxxxxxxxxxxxxxxx>]

I've had "BUG: soft lockup - CPU#1 stuck for 61s! [udevd:4865]" happen
twice now and the server fairly quickly (over the course of 5-10
minutes) becomes unusable after that happens. The call trace appears to
be:

Call Trace:
 [<ffffffff8100e8e9>] ? xen_force_evtchn_callback+0x9/0xa
 [<ffffffff8100ef72>] ? check_events+0x12/0x20
 [<ffffffff8100ef19>] ? xen_irq_enable_direct_end+0x0/0x7
 [<ffffffff8102fcc1>] ? do_page_fault+0x9e/0x27b
 [<ffffffff812b39a5>] ? page_fault+0x25/0x30

 [<ffffffff81045265>] ? schedule_tail+0x92/0x96
 [<ffffffff81011983>] ? ret_from_fork+0x13/0x80

That was under 2.6.32.17-g69a73fa. I've since upgraded to
2.6.32.18-ge6b9b2c but the changelogs don't show anything obviously
related to the crash (but as usual there are a lot of them so maybe I've
missed something?)

Is this a known problem under 2.6.32.17-g69a73fa that has since been
fixed?

Thanks

James
