I've had some trouble with that off and on, the symptom usually being
garbled sound output, but I've been running 2.6.16 for a while now,
and light sound usage seems to be Ok. Alsa modules,
$ lsmod

sound 75744 2 waveartist
soundcore 7716 2 sound
Recently I've had another problem: the DEC/tulip port (eth0 on my
setup) has started dropping link for ~1 second at a time under heavy
usage, which I really notice when playing quake/etc (my netwinder is
my firewall, I don't play quake on it). I read on the FAQ that the
link LED on the netwinder is inverted, but I can see the link go down
on the switch side,

I've been running 2.6.16 since last October, and this only started
happening a few weeks ago. I've tried different cables, different
ports on the switch, to no avail.
Even if I retire it as my firewall, its still a neat little machine to
have around. I might try and revive the video-input/output one of
these days.
