I don't recommend this patch. It disables updates to resource descriptors in
some cases, which means you'll get resource bindings from old draw packets =
or
even old IBs, which will cause VM faults or even hangs. I think it also bre=
aks
MSAA and might cause hangs there too (CMASK must be cleared).

Hawaii works without the patch very well here. I'm only using Alex's stuff =
from
comment 81 and my Mesa fixes. N=
othing else.
