Package: xen-linux-system-2.6.18-5-xen-amd64 Version: 2.6.18.dfsg.1-13etch2 Severity: critical Justification: breaks the whole system
On a dual-processor, quad-core Xeon system, after running successfully for a few days, I created and then started another domU (the 4th one, I think), resulting in a kernel panic requiring a hard reset. After changing dom0-cpus to 1, this problem has not reoccurred. However, using 1 core out of 8 makes this workaround pretty worthless.
