I got the following on the April 1st nightly source release of the unstable tree. 2 CPU machine, SMP not configured, default configs for dom0 (256MB) and dom1 (512MB). Idle system for the most part, and I wasn''t at the machine, came back to find this scrolling of my screen and in /var/log messages. Dom1 was hosed. Had to reboot subsequently. Ran some tests (netperf) between dom0 and dom1 to see if I could reproduce it, but haven''t. I''ve since upgraded to 4/12/05 nightly snapshot. Haven''t seen it again yet. Does this look like a valid kernel/oops? Any info that I could dig up?
