So PIPE_USAGE_STREAM seems to be a main problem again,
Note that this could be due to the application or non-driver Gallium code incorrectly using PIPE_USAGE_STREAM.
but unlike 64bit on 32bit it can't be reverted to old behavior, on 32bit it is unusable produce much corruption.
Weird, sounds like a kernel issue.
