Comment 9 for bug 891115

This is not related to Xen. I'm running a small file server at home with Ubuntu Server 11.10 and an LSI MegaRAID 8480E controller and I've been getting the same errors and the card going offline randomly. Aside from the listed output above from syslog there's no errors or logs that can be taken of this problem.

I have a theory I'm testing that it might be heat related. It's happened to me 3 times and the last two times it happened the heat sink on the controller was burning hot. I've applied new compound and added a small fan to it. I'll post back my results, it may take a couple days to fully test.
