Hello Yang,

The problem that we are discussing here seems to come from the 
interaction of my raid controller (Areca, ARC-1212) and the hardware.
When I enable MSI on that controller the server crashes with the known 
error messages between 1 day and 7 days.  When I disable MSI I don't see 
these crashes anymore.

Andrew doesn't have this controller but he could also observe these type 
of crashes with another MSI enabled card, I think the networc card. But 
less often, I think 2 times in the last 4 months.

My cpuinfo nor dmesg show any microcode information, perhaps Xen hides 
that info ?!

Best regards
   Thimo
