Haven't had time to test thoroughly, but I see the latest updated agd5f fixes
has a commit to reduce vm faults and I haven't got thousands since changing to
that.

I also see a new R600_DEBUG=check_vm in mesa. I don't know what, if any, extra
info is expected from that, but testing valley with it caused it to quit when
it hit a fault after a about minute of running -

Detected a VM fault, exiting...

in dmesg -
