I just updated my quad-processor X64 machine (AMD Phenom(tm) II X4 945 Processor) to the latest CentOS 5 xen kernel (2.6.18-371.4.1.el5xen) and I am getting occasional "BUG: soft lockup - CPU#n stuck for X s!

Hi all, sorry to intrude on xen-devel, but I think I need direction from the expertise here. I''ve admin''d Xen servers of various flavors for a couple years, but never seen this before. After a period ranging from several hours to several days, my primary database and development DomU completely locks up. Net disconnects, but CPU(sec) continues to tick in xentop. No errors, and

Dear list, I am seeing an error across multiple machines during heavy I/O, either disk or network. The VMs are on different Intel CPUs (Core 2 Quad, Core i5, Xeon) with varying boards (Abit, Asus, Supermicro). Machines that get this error are running either BackupPC, Zabbix (MySQL) or SABNZBd. I can also reproduce the error on the Supermicros with a looped wget of an ubuntu ISO as they are
