[Dri-devel] DRI Mach64 Freeze When atmel_cs loads in 2.6.1

[Adam K. <ad...@bo...>]

I've been trying to get mach64 DRI to work under 2.6.1. I saw an earlier
thread here talking about a patch, but the patch attachment didn't make
it in to the sourceforge archive.

I did apply the patch described here:

<http://www.hjsoft.com/blog/link/Mach64_DRI_on_Linux_2.6>

which actually compiled and I am now able to use mach64/DRI under 2.6.1.
As soon as my wireless card driver (atmel_cs) loads, however, the system
goes into a hard lock and needs to be powered cycle (no SOS kernel
panic).

Is there a better patch for mach64/2.6.1? Is this an atmel problem, a
mach64 problem, or a kernel problem? Any suggestions for getting DRI to
work with my PCMCIA wireless card?

I see the following in syslog; the handlers: and call trace: line are
repeated dozens of times:
