Public bug reported:
I ignored my system for a while, long enough for the screensaver to
blank the screen. When I tried to get it to awake ( I don't need to log
back in), it seemed to be semihung, showing pretty black screen, but a
mouse cursor visible. It did not respond to hitting keys. I tried
switching back and forth between VT1 and VT2 to get it to come back to
life. Eventually it came back on its own, but it took too long.
Here's a chunk of log from the time this happened. There are on the
order of 2000 of the "maximum number of pending replies" messages that
you see at the end of this log snippet.
