Ugh, it happened again.  This time I exited X windows just when starting
to notice problems (the audio player for example stopped playing) and
X became irresponsible (though I could move the mouse).

When in the console, I saw that message appearing continuously, but it
didn't crash.  I.e., I had no network connectivity at all, and some

is nfs-mounted.)

a year), but it hadn't caused any more issues up until now :(  Dunno
if this has something to do with my recent upgrade from 2.99.10 to
