Created attachment 448036 [details] /var/log/messages during nvaf acceleration failure The drm-nouveau-nva3-noaccel.patch disables acceleration for certain chipsets - a3, a5, a8. My nvaf system seems to behave quite badly with accel turned on: the screen is drawn without any text, for instance. A lot of PGRAPH_ILLEGAL_CLASS/MTHD messages appear in syslog from nouveau - for example: Allocating FIFO number 3 nouveau_channel_alloc: initialised FIFO 3 PGRAPH_ILLEGAL_CLASS - Ch 3/7 Class 0x8597 Mthd 0x0000 Data 0x00000000:0x00000e20 PGRAPH_ILLEGAL_MTHD - Ch 3/7 Class 0x8597 Mthd 0x1558 Data 0x00000000:0x00000001 [etc] Adding 'case 0xaf:' to the switch statement added in drm-nouveau-nva3-noaccel.patch makes the system usable again. I'm attaching the logs in hopes that they might be useful to trace the actual problem - since the system doesn't actually lock up, this might be a different problem from a3/a5/a8 - but in the meantime I'm guessing we will need noaccel=1 for nvaf.
Oh - obviously putting 'nouveau.noaccel=1' on the boot commandline is an effective workaround.
