Recent Failure Reports:
GPU is a Radeon HD 7870, using radeonsi git 2014.04.21 (7cb3bbf) from oibaf ppa
recompiled with llvm 3.5 (svn 206757).
Even after bug #60929 was fixed I have been experiencing system hangs with
LITTLE Racers Street, which is based on mono. The hang usually happens randomly
after a few races have been played and results in the image in the screen
getting its colors corrupted (just like when in old times you changed the color
depth in windows 95 -I'll try to get a picture with a camera because the system
is hard locked-) and a loop in the sound. So just a hard lock.
I did not know what was to blame and was waiting for a game update in order to
see if things got solved.
However, I have recently bought Foosball Street Edition (also based on mono).
The game launches and shows the menus OK, but hangs the system at about 5-10
secs after the kick-off of any match. The hang is not like LITTLE Racers
Street, but rather like a series of GPU hangs and recoveries (screen goes black
and then shows the game a few times in a row) which end up in the system
totally frozen. During that time there is no sound playing. So probably not a
lock as hard as in LITTLE Racers Street.
I'm not sure how to debug this but I am quite convinced that this could be
another case of mono + llvm backend incompatibility. The reason for that belief
is that (i) I have tested this game on this same PC with catalyst and the game
does not hang and everything works wonderfully, (ii) I obtained the same good
results in a laptop with a Radeon HD 4570 (r600g, not llvm) (mesa git from
around 10 April); and (iii) both games are based on mono.
As stated above, I'm not sure how to debug this because when the system hangs,
it does not allow VT switching to check the logs or the dmesg output. I would
be happy to help with any further information needed.
