RE: [Xen-devel] Errors when build 2.6.31-rc8
I’ve had the same problem since his Jeremy’s branch went from
rc6 to rc8 this week. I can boot the kernel on bare metal, but not under Xen
as dom0.

After this change:-
-*- /dev/agpgart (AGP Support)
--->
< > Direct Rendering Manager (XFree86 4.1.0 and higher DRI
support)
i was able to build 2.6.31-rc8 (with Xen Dom0 support).
However, attempt to load 2.6.31-rc8 either under Xen 3.5 or Xen 3.4.1 causes
console to drop into stack trace and hangs.
Thank you.
Boris.

I think there is a conflict between the newer drm code and swiotlb. I have
seen this for a while on my Fedora builds as Fedora Rawhide seems to get the
new drm code before it makes it into the official kernel. You can work around
it by disabling a small number of drm related kernel options, though you
probably lose some functionality by doing so.
