Dave,
I found why my G5 was crashing when using the linux-2.6 version of the
DRM + git-drm.patch from 2.6.13-rc6-mm1, but not with the CVS DRM.
The reason was that dev->agp->cant_use_aperture wasn't getting set,
and the reason for that was that <linux/version.h> no longer gets
included and the #if LINUX_VERSION_CODE < 0x020408 in drm_agpsupport.c
was going the wrong way. With this patch (and a few others) a 32-bit
server works correctly, as does DRI.
I still don't have a 64-bit X server working though. The X server
gets a certain distance and then the CPU that it is running on just
freezes solid - it doesn't even respond to a soft reset. This isn't a
DRI problem, though, since it happens without the DRM loaded.
Regards,
Paul.
