Unfortunately there is still a problem with it, at least with NetBSD 3.1.1.

I like to hear to a radio live stream while compiling and developing, and
after a few minutes it happened: complete lockup of the system! The only
life-sign was that I could still ping the machine, but not log-in.

This is a PowerMac G4 (Sawtooth) 400 MHz with 1.25 GB RAM. The load was not
too high (mainly caused by Firefox). I was just starting a new live stream on
xmms when it happened.

Did the interrupt code improve from 3.1 to 4.0, or in current? Then I might
test that again.
