I tested this VIA Chrome9 DRM driver under Ubuntu 9.10 and its patched
2.6.31.4 kernel. It loads fine, bus as soon as I start my openchrome Xserver
(compiled for 1.6.4, module version = 0.2.904) I get following Oops:

I know this kernel module is made for VIAs own X.org driver and not openchrome
but:
1. I don't think userspace should be able to easily trigger a kernel oops, and
2. Can't this new VIA Chrome9 DRM interface be made more compatible to the
existing one? Ideally it would "simply work" with the existing/slightly
modified (with the support from VIA?!) opensource openchrome driver...
Kind regards,
Thomas
