Nope, its a userspace driver problem.. we have not released
non-experimental code for that chipset, so its not surprising it fails
when the kernel code gets run, but the fix most likely is in userspace not
in the kernel.

I could disable the userspace DRI code but then where would I find my
testers .. if he reads his Xorg log it says DRI is experimental on rs690
and not to come crying..

this is the problem with adding new chipsets, I either wait for 6 months
for all the bugs to get kicked out so nobody wins, or I push it upstream
so most people win, I could back this out of the kernel, but experimental
userspace code isn't a reason for this..

Dave.
