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 mem_kb=131072 ssidref=-1 dom=3 [2005-08-27 20:21:06 xend] DEBUG (XendDomainInfo:780) init_domain> Created domain=3 name=samba-ha memory=128 [2005-08-27 20:21:06 xend] INFO (XendRoot:141) EVENT> xend.domain.create ['samba-ha', 3] [2005-08-27 20:21:06 xend] INFO (image:208) buildDomain os=linux dom=3 vcpus=1 [2005-08-27 20:21:06 xend] INFO (xsobj:326) DBMap>introduceDomain> 3 5882 <EventChannel dom1:0:18 dom2:3:2> /domain/838ae36b-66f8$[2005-08-27 20:21:06 xend] DEBUG (XendDomainInfo:640) writing key availability=online to path /cpu/0 in store [2005-08-27 20:21:06 xend] WARNING (XendDomainInfo:1032) Unknown config field boot [2005-08-27 20:21:06 xend] WARNING (XendDomainInfo:1032) Unknown config field display [2005-08-27 20:21:06 xend] ERROR (XendDomainInfo:425) ['vif', ['mac', 'aa:00:00:7e:cb:8c'], ['bridge', 'xen-br0']]

[2005-08-27 20:21:06 xend] INFO (XendRoot:141) EVENT> 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,
