[Xen-devel] Kernel BUG at "drivers/xen/blkfront/blkfront.c":95

[Robin van Leeuwen <rvl@xxxxxxxxxxx>]

When i boot my domU on amd64 (debian unstable)
i get during startup in xend.log:

[2005-08-27 20:21:06 xend] DEBUG (image:153) initDomain: cpu=-1

xend.domain.unpause ['samba-ha', 3]
But my domain works fine. After a while (+/- 5 or 8 minutes the 
following message appears:
(i'm not sure if the n/ testing main was generated by the bug, i was 
editting /etc/apt/sources.list
when it happend)

----------- [cut here ] --------- [please bite here ] ---------
Kernel BUG at "drivers/xen/blkfront/blkfront.c":95n/ testing main
invalid operand: 0000 [1] SMP
CPU 0 Modules linked in: md5 ipv6 ext3 jbd
Pid: 30, comm: pdflush

The domain stops responding on console and network. xm list shows:
samba-ha           3      128    0      1   -----   2496.0

xm top shows:
3 ------       2739   98.4     131072    6.3     131072       6.3     
1    1      110     3422    0
so it's pretty musy doing something...

any more info needed?

kind regards,

Robin van Leeuwen
