The GPU lock with Rv670 and openarena is nothing new - it seems to have been a
feature for almost a year (I haven't used rv670 for most of that time).

On noticing the new gpu reset code in drm-next-3.9-wip I decided to provoke it
on my AGP box and got -

Hmm I just managed to get the same running drm-fixes so it's not wip maybe it's
because I am now using llvm. In the (no llvm) past with other kernels this GPU
lock normally went quite well - the game often just continued for a while,
until it hit another one.

It's nothing to do with llvm seems like it's a feature of more recent kernels.

Hardware is a HD 5470 (ChipID = 0x68e0)

Google points me to several bugreports from Red Hat/Fedora, so this bug seems
to be not uncommon.

Old - no h/w to test so closing.

Johannes if you can still produce this with current kernels etc please re-open.
