Commen= t # 11 on bug 75061<= /a> from Michel D=C3=A4nzer 
AFAICT the problem is that both threads access the same struct=
 r600_resource
concurrently. It might be relatively easy to avoid the crashes by updating =
the
buf member atomically in r600_init_resource() instead of setting it to NULL
first in r600_invalidate_buffer(), but I suspect there could be more subtle
issues with other members, in particular valid_buffer_range.

Marek, any thoughts on how to solve this?
