[Vasiliy Tolstov]

Hello. I'm try to run domU kernel from backports.debian.org under 32
bit guest (686-pae), but after sometime i get error in dmesg:

http://cdn.selfip.ru/hang.png

in guest loaded only xen-netfront.ko module.

It means it is stuck waiting for a change.
What is your Xen/dom0? IT could be that it is missing some patch?
Did you try the xen-unstable and Linux v3.2?

I have SLES kernel-xen-2.6.32.36-0.5.2 and xen-4.0.1_21326_06-0.4.1,
i'm not try latest xen versions.
SLES does not provide kernels for 3.x and not provide xen versions > 4.0.xx =(

The SP1 update channel has a 4.0.2 based xen package since some time,
also a newer kernel.
I guess to debug this hang further some host logs are needed (xend.log,
qemu-domU.log, etc.), and also the domU config file.
