Thread-topic: [Xen-devel] i915 crashs in the pvops dom0
I searched my issue with Google, and found that someone has already reported 
this issue in 
http://lists.xensource.com/archives/html/xen-bugs/2010-04/msg00021.html, but I 
didn't find any solution.
It may be caused by PFN != MFN issue.

Here is my grub.conf:
Root (hd0,1)
Kernel   /xen-4.0.0.gz dom0_mem=2G
Module  /vmlinuz-2.6.31.13 ro root=/dev/VolGroup00/LogVol00
Module  /initrd-2.6.31.13.img


Thanks
Ben

Take a look at this:
http://wiki.xensource.com/xenwiki/XenPVOPSDRM

How much memory does your dom0 have?
Also please paste your dom0 grub.conf.
