Public bug reported:
Just after the screen freezes, I am sometimes able to log in with SSH
and the log file typically reads:
Feb 26 11:18:15 is233895 kernel: [15385.625416] nouveau 0000:01:00.0: fifo:

However, the machine eventually locks up and I cannot log in with SSH
any more. Then I need to power down the computer.
