About one time in four, when I boot up the machine and log into GNOME, all I get is a dark grey screen with a mouse cursor on it. If I successfully log in, the card works pretty well for a while - could be many days, but might be only half an hour - and then eventually it will suddenly hang.
In the X log, there’s this:
(EE) [mi] EQ overflowing. Additional events will be discarded until existing events are processed.
(EE) [mi] mieq is NOT the cause. It is a victim.
(EE) [mi] EQ overflow continuing. 100 events have been dropped.
[ 39801.202] (WW) NVIDIA(0): WAIT (2, 8, 0x8000, 0x00001d2c, 0x00001d34)
[ 39808.202] (WW) NVIDIA(0): WAIT (1, 8, 0x8000, 0x00001d2c, 0x00001d34)
[ 39808.204] [mi] Increasing EQ size to 1024 to prevent dropped events.
[ 39808.205] [mi] EQ processing has resumed after 2177 dropped events.
[ 39808.205] [mi] This may be caused my a misbehaving driver monopolizing the server’s resources.
and finally more of this:
[ 39848.336] (WW) NVIDIA(0): WAIT (2, 8, 0x8000, 0x00001d2c, 0x00001d3c)
[ 39855.336] (WW) NVIDIA(0): WAIT (1, 8, 0x8000, 0x00001d2c, 0x00001d3c)
[ 40252.395] (WW) NVIDIA(0): WAIT (2-S, 17, 0x07e2, 0x00001d2c, 0x00001de0)
The graphics system is essentially dead until the machine is reset, though occasionally it might be possible to kill the X server and restart it. Usually though I’ll need to shut the machine down completely, and occasionally it won’t even go down and has to be hard-reset with the power button.
This is really frustrating, as the crash has happened three times so far tonight. :-(
