Two more crashes to report. This time, it happened with oss_ich
loaded on the same machine that's showing the above crashes (with
oss_sblive), and a completely different machine using oss_hdaudio. The
latter machine may not be crashing as often simply because I'm not in
front of it as much as the former machine.
Here's the backtrace from the oss_ich chipset:
