VIRIDIAN CRASH: 3b c0000096 75b12c5 9e7f1580 0

[James Dingwall <james-xen@xxxxxxxxxxxxxx>]

Hi,

I am building the xen 4.11 branch at 
310ab79875cb705cc2c7daddff412b5a4899f8c9 which includes commit 
3b5de119f0399cbe745502cb6ebd5e6633cc139c "86/msr: fix handling of 
MSR_IA32_PERF_{STATUS/CTL}".  I think this should address this error 
recorded in xen's dmesg:

(XEN) d11v0 VIRIDIAN CRASH: 3b c0000096 75b12c5 9e7f1580 0

I have removed `viridian = [..]` from the xen config nut still get this 
reliably when launching PassMark Performance Test and it is collecting 
CPU information.

This is recorded in the domain qemu-dm log:

The Windows guest is running winpv drivers 8.2.1.

I'm not quite sure what else to examine or change at this point so any 
guidance would be welcome.

Thanks,
