[pkg-nvidia-devel] Bug#570365: nvidia-glx: problem confirmed in with latest xen hypervisor

[Michel Briand]

Package: nvidia-glx
Version: 195.36.24-4
Severity: normal

Tested theses setup:

1/
xen hypervisor 4.0.1~rc3-1
+ linux-image "xen" (linux-image-2.6.32-bpo.5-xen-amd64)
+ nvidia 195.36.24 built from dkms

2/
linux-image "xen" (linux-image-2.6.32-bpo.5-xen-amd64)
+ nvidia 195.36.24 built from dkms

3/
linux-image "without xen" (linux-image-2.6.32-bpo.5-amd64)
+ nvidia 195.36.24 built from dkms

Test results: 1 fails, whereas 2 and 3 work.
When the system fails, we have the message:

   Xorg: Corrupted page table

Tests 2 and 3 work well: launched successfully glxinfo, 
glxgears and openarena.

Maybe this bug is related to #470817 ?

Test results point at a problem between Xen Hypervisor and 
NVIDIA driver memory management.

Best regards,
Michel
