Subject: 3.10-rc1 guest kernel panic : known issue ?

Hello,
On a Westmere EX system I tried to boot a 3.10-rc1 kernel in the guest
and tripped over a panic.
[ 'was only able to capture part of the info. on the guest console...
Pl. see the JPG file and also the qemu command line below. ]
'am using qemu (from qemu.git 1.4.91) that is about a day old. This
worked fine with 3.9-rc7 kernels in the guest.
I had also tried smaller guests with and without VFIO and huge pages
etc...and got the same panic.
Is this a known issue [or an operator error on my part] ?
Thanks
Vinod
