thanks for all the fixes !
currently using
http://cgit.freedesktop.org/~agd5f/linux/log/?h=drm-next-3.17-rebased-on-fixes
and it looks pretty stable so far (radeonsi, R9 270X)
even with 3.14.14 there were some (pretty seldom) but occasional crashes of X:
vanilla 3.16-rc6 was pretty much unusable (X + box hardlocks)
and especially http://cgit.freedesktop.org/~agd5f/linux/?h=drm-next-3.17-wip
(*without* the fixes) had dozens of gpu crashes yesterday evening/night which
were recovering (probably thanks to radeon.hard_reset=1) without crashing X and
hardlocking the system:
ring 0 stalled for more than 10010msec GPU lockup
waiting for ... last fence id ... on ring 0
GPU softreset ...
[drm] UVD initialized successfully.

and

(WW) RADEON(0): Page flip failed: Invalid argument
currently still running with radeon.hard_reset=1 - but that probably shouldn't
be needed anymore
best trigger for those occasional crashes was using chromium/chrome, watching
videos on youtube, switching apps via alt+tab (using an composited desktop with
compiz-fusion 0.8.8) and from time to time opening up gmail (which, if I
remember correctly would cause the gpu to crash at least twice of these
countless times yesterday)
