           Version: unstable
          Platform: x86-64

System description:

Compaq DL 145 with Opteron 3 gb ram
Dom0 running debian Sarge with iscsi support
domU running debian Sarge, normal kernel not patched 
running changeset 7901

This release seems to be working fine, have done some benchmarking (web server) 
on it, with no issues, but after several hours (mostly happens at night)
the kernel in DomU oopses. When this happens Xentop show 99% cpu usage for that
domain, it usually happens to al DomU's, but i am running with only 1 DomU at
the moment.
It is then possible to restart/shutdown the domU en restart it.
xm console does show the oops:

domU config:

kernel = "/boot/vmlinuz-2.6.12-xenU"
memory = 256
name = "cust-01"
vif = [ 'mac=aa:01:02:03:04:11, bridge=xenbr0' ]
disk = [ 'phy:sdb,hda1,w','phy:/dev/raid1/swap-kraaybeek,hdb1,w' ]
root = "/dev/hda1 ro"
extra = "2"
on_reboot   = 'restart'
on_crash    = 'restart'
