OpenSUSE Network :: Installation In Xen Freeze Whole Computer From NFS?

I have host server for xen (11.2 x86_64) and another server holding linux images. Those images are accesible via NFS.

When I am installing new machine on my xen host and using images on nfs share; whole host-machine freeze during installation (random time, random packages, but it freeze everytime). I had to hard rebooted. Machine do not respond to ping. Performing same installaltion from local copy of same image (copy is done through NFS !) is always vithout any problem.

Xen host machine is MSI Wind and it have gb ethernet. I had some problem with it on Windows XP (disconecting) but on Windows Vista it was ok. On Linux I also did not encounter any problem so far.

Strange thing is that after hang there is no error in /var/log/messages. I would like to investigate what`s going on, what cause this freeze.

I am thing about sysrq messages, but this machine do not have any com port.

Here is output of lspci just for info
