This kernel panic occurs when running a kvm guest, usually with minimal
cpu/disk/network activity. What might I try to correct it?
------
Host
- unpatched kernel 2.6.39-rc1 with default .config options
- also on debian 2.6.37-2 and 2.6.38-2
- kvm 0.14.0+dfsg-1~tls
- br0 on single intel igb NIC (3 other NIC's unused)
- br0 with ip address on distinct /27 subnet
- br0:1 with ip address on distinct /24 subnet
- br0:2 with ip address on distinct /24 subnet
Guest
- Debian Squeeze stable image with stock kernel and modules
- virtio block and net devices
- eth0 with ip address on same subnet as br0
- eth0:1 with ip address on same subnet as br0:2
