Dietmar,
This is a known issue with WLAN passthrough cause by ME
(management engine) interaction. The latest xen-unstable has quirk to
workaround issue.
Can you give it a try and let me know if it fixes the problem
for you? By the way, which brand of Core i5 laptop do you have. I
would like to see if I have one locally.
Allen

Subject: [Xen-devel] Problem: WIndows domu switches power off
Hi list,
I
have a special effect on a Laptop with:
cpu: Intel(R) Core(TM) i5 CPU
M 540 @ 2.53GHz with integrated graphics
Chipsatz: Intel QM57
with SLES11 SP1 (xen-4.0 with
some patches from Novell)
I
passed through the sound and WLAN pci controller to the guest.
I
start a Windows 7 guest and while installing the driver for the WLAN
controller within Windows the
power of the notebook got switched off.
I couldnt see any message on
the serial console.
I tried Windows on bare
metall and all runs very well. Later on starting this
Windows guest again the power
got switched of after login into Windows - maybe
the WLAN driver got started
there.
For a test I prepared a
OpenSuSE 11.3 as HVM guest and were able to configure
the WLAN device without any
problems.
And here I need some
assistance to prevent the power off and to add some tracer
in the hypervisor.
By the way I have no problems
with the sound device.
If wanted I can add more
informations.
Thanks.
Dietmar.
