Hi,

I'm running kvm-75 with a Fedora 10 (rawhide kernel version
2.6.27-0.323.rc6.fc10.i686) guest using a virtio NIC.  As soon as I
stress the network (e.g., mount a CIFS volume and start a build) I get
the following kernel BUG.  If I boot the system to the older F9 kernel
(2.6.25.11-97.fc9.i686) I don't see the error.  There are several other
traces after this one, but I expect they're collateral damage.
