live dmesg before X was started
When I start nouveau with 2D acceleration the framebuffer is unusable
(typically displays frozen contents of the last shutdown), but the keyboard is
responsive. Once X starts, the display is unreadable - anything to a tiled
staircase picture to a partially solid grey screen, with no mouse cursor, and
the keyboard locks up - no responsive from the caps/num/scroll locks keys,
however it DOES respond to Magic SysRQ. The machine itself doesn't seem hard
locked, though.
The syslog is spammed with tons of message from the nouveau driver complaining
about PFIFO_CACHE_ERROR, PFIFO_DMA_PUSHER: MEM_FAULT, INVALID_CMD,
CALL_SUBR_ACTIVE, etc - varies wildly on each boot. Sometimes its only few
errors, sometimes tons of them, but the end result is the same.
Tried with the nouveau git tree on freedesktop 2/23. using nouveau.nofbaccel=1
clears up the framebuffer corruption, but the X display corruption/lockups
still happen
