http://bugzilla.xensource.com/bugzilla/show_bug.cgi?id=1164 Summary: Dom0 "BUG: soft lockup detected on CPU#0!", (ntpd?) Product: Xen Version: 3.0.3 Platform: x86 OS/Version: Linux-2.6 Status: NEW Severity: normal Priority: P2 Component: Hypervisor AssignedTo: xen-bugs@xxxxxxxxxxxxxxxxxxx ReportedBy: jason@xxxxxxxxx I am trying to diagnose why this Xen box keeps crashing every 2-3 days. It is on Centos5 with the latest Xen and all updates from the repository. I'm getting these in /var/log/messages a few minutes before some ntpd messages (see log below). Any ideas?
