Re: [Xen-devel] cpuidle and un-eoid interrupts at the local apic


I've looked it up in the bios, microcode version is 9

Best regards

Probably you can use a non-Xen kernel to boot up the system, and then you can 
get the micro-code in cpuinfo.  Thanks!

unfortunately the Xenserver kernel seems to not support reading the microcode, 
at least it is not populated in /proc/cpuinfo.
Andrew, are there any special tricks to get the version out of the Xenserver 
kernel ?

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 ?!
'cat /proc/cpuinfo' will show the microcode version.
