RE: [Xen-devel] Problem: WIndows domu switches power off

["Kay, Allen M" <allen.m.kay@xxxxxxxxx>]

Dietmar,

 

Can you try the attached patch?  I have included your WLAN device 0x422c8086.

 

I have not seen the power off problem on the OEM Calpella laptops I’m working with (Lenovo and Dell).  I can assign Wifi to win7 without causing system problems.  The drivers cannot start though on these OEM platforms due to wifi driver checking some platform id. I need to research into this.

 

 I can assign wifi to win7 on my Intel SDP without any problems.

 

 Allen

It took a while but today I tested with xen-unstable from monday, 22. Nov.

I could login into windows and scan for wlan networks, 2 were found and then

the power of the laptop got switched off :-(

Are you knowing a way to avoid the power off or how to trace this behaviour?

Thanks.

Dietmar.
