Interestingly enough, under 2.1.64, my version of squake causes a kernel oops when you /exit/ the program. It runs perfectly until this time. The oops doesn't shut down the system. In fact, it doesn't seem to cause any problems at all. The oops I get:

This is definitely kernel related. It works fine with 2.0.32 and below. I'm not sure if that dev/dsp means the problem is related to the sound driver or what...
Speaking of sound drivers, is there anyone working seriously on kernel sound support? What I'm interested in is full duplex on Creative cards. I've heard with only one IRQ they can't be actually full duplex cards... Nevertheless, they have full duplex Win95 drivers, I presume by toggling between read/write very quickly or another such gimmick. However, if this can be done under WinDoze, presumably its something that can be done under Linux. :) It would be nice to be able to do SpeakFreely without having to toggle CB radio style all the time...
