Can't boot 8/CURRENT hvm on Quad-Core Opteron 2352

[Timothy Bisson]

Hi,

I'm trying to run a FreeBSD 8/CURRENT hvm on XEN, but booting FreeBSD  
currently panics on a quad-core Operton 2352 box while booting from  
the iso (disabling ACPI doesn't help).

However, I'm successful at running a FreeBSD 8/CURRENT hvm on XEN on a  
Intel Xeon Nehalem box. I tried booting the same installed disk image  
(from the Nehalem box) on the Operteron box, but that also resulted in  
a panic while booting.

The CURRENT iso I'm using is from:
ftp://ftp.freebsd.org/pub/FreeBSD/snapshots/201001/FreeBSD-9.0-CURRENT-201001-amd64-bootonly.iso

I'm using Xen-3.3.1 on both physical boxes, and a BSD 6 hvm works on  
both the Nehalem and Operton boxes...

Here's the backtrace from the opteron box:
kernel trap 9 with interrupts disabled

I took a look through the bug database and didn't see any similar  
problem reports. Is it reasonable to file a bug report? Is there  
additional information that I should be reporting?

Thanks,
Tim
