Apparently I am having the same problem with KVM-62 in Ubuntu Hardy Heron server amd64 with kernel 2.6.24-19-server. At the moment it has happened a single time, but I can confirm that the VM is under heavy IO load. Even so this it is a _very_ serious problem from the moment that the VM is a productive host.

KVM start configuration:

# APS2
$KVM -hda /dev/vm/aps2-raiz -hdb /dev/vm/aps2-space \
 -hdc /dev/vm/aps2-index -hdd /dev/vm/aps2-cache -m 4096 -smp 4 \
 -net nic,vlan=0,macaddr=00:16:3E:00:00:27 -net tap -daemonize -vnc :5 -k es \
 -localtime -monitor telnet:localhost:4005,server,nowait \
 -serial telnet:localhost:4045,server,nowait

Next, I copy the lines found in /var/log/messages:

Hardware:

HP Proliant DL380 G5
2 x Xeon QuadCore - 2 GHz
16 GiB RAM / 1 GiB swap
Network interface: 2 x NC373i 10 / 100 / 1000
HP Smart Array E200 with 8 x 300 GB SAS - 10k / RAID 5.

The VM is running Debian GNU/Linux Lenny 5.0.2 with kernel 2.6.26-2-686 and 'pci=noacpi' kernel option in order to avoid transmit timed out from network interface which turn it inaccessible to the rest of the network. Both /var/log/messages and /var/log/syslog in the VM don't show messages of IDE DMA callback problems.
