Hi Liu,
> Any update? I need reproduce the bug so your environment/config is really
> needed.
I think I have some news, finally. I got a docking station and a serial
cable and was finally able to capture some more debug output. You were
right, the hypervisor seems top be still alive (but timers seen to be
stalled). When the problem occurs, I see
(XEN) Platform timer appears to have unexpectedly wrapped 10 or more times.
This has been reported elsewhere, but I haven't seen anyone reporting a
total freeze in this case, like me.
I am attaching a serial capure. When the problem occured, I switched the
serial port to the hypervisor and ran some diagnostics. Hints
appreciated. This was done with the hypervisor and kernel of OpenSUSE 11.4.
xen-4.0.2_02-4.7.1.i586
kernel-xen-2.6.37.1-1.2.2.i586

I haven't seen it on any other machine. But I don't have a
representative set of machines, either.
