[Xen-devel] Xen-4.0/linux-pvops: System hangup/crash after exiting X

[Mark Hurenkamp <mark.hurenkamp@xxxxxxxxx>]

Hi,


Using current xen-4.0-rc4 and recent linux-pvops i have a problem  
whenever i exit X to go back to console, the following is printed
on the serial console:
(XEN) mm.c:3847:d0 Bad page 0000000000072e99: ed=ffff83017fef0000(0),

^^^ repeated thousands of lines (with a different page number) ^^^

With an older xen-4.0-rc3-pre, this also happened, but it seemed to  
recover from this after a 60-90 seconds stall, and so i never really  
regarded this as
a big problem, but now it won't recover anymore, which makes it  
impossible to shutdown the system properly after use.
Can anyone tell me what is happening here?
And more importantly, is there anything i can do to fix this?


Regards,
Mark.


B.t.w. This is on an Asus P7P55D-Evo/Intel i5, ubuntu karmic, and open  
source radeon driver with a HD4350 card.
