[Xen-devel] vcpu-pin cause dom0 kernel panic

[Andrew Xu <xu.an@xxxxxxxxxx>]

I use xen 4.0(dom0 is suse11.sp1,2.6.32 x86_64) on 
Dell R710 with PERC H700 RAID adapter.
--Intel(R) Xeon(R) CPU E5620 @ 2.40GHz
--8 CPU cores.
--Memory 64G
--RAID5 4.5T

When I dedicated (pin) a CPU core only for dom0 use.
(I specify "dom0_max_vcpus=1 dom0_vcpus_pin" options for Xen)
I got dom0 kernel panic error(pin-1-5.30.bmp)

When I pin 2 core to dom0, the dom0 system can boot up,
but it can't find any disk devices.

But when I pin 4 core to dom0, it run OK.

Does anyone can help me, please.

I have read this mail, and updated my megaraid_sas to version 05.30.
