I upgraded the base system from r355127 to r355521.
However, I now think I may have sounded an alarm too soon. After posting that
note, I went to sleep for a few hours. When I woke and returned to the machine, it
took me four or five minutes to notice--I was still half asleep--that the image on
the screen was no longer behaving in the previous, offensive manner. I have also
seen a number of crashes since then, and I now believe the machine is having some
hardware stability problems.
Some of the crashes have left messages in /var/log/messages like these.
drmn0: ring 0 stalled for more than 10011msec
drmn0: GPU lockup (current fence id 0x0000000000029cee last fence id 0x0000000000029d02 on ring 0)
drmn0: failed to get a new IB (-11)
[drm:radeon_cs_ib_fill] Failed to get ib !
drmn0: Saved 631 dwords of commands on ring 0.
The above are then followed immediately in /var/log/messages by the FreeBSD copyright
notices that always appear first in the boot messages. I do not know whether the GPU
lockups are due to hardware failures or GPU software crashes, but the system always
tries to reboot after a few seconds, during which time it is unresponsive. No crash
dump is produced in these crashes.
