Now that I know somebody else has the problem, I'm likely to do more about it. I suspect your kernel panic is likely to be the same as mine (which still happens with 5.1-BETA as of a couple of weeks ago). >BUT I have done alittle testing.

This tends to support my idea. If anything sharing irq 9 gets an interrupt, all the things on irq 9 get a chance to run. This includes the sound card, so the driver then notices it has interrupts and does stuff with them. Other than trying to get the sound interrupts working (a thing I don't know how to do) I can't suggest much else. The flood ping is an interesting idea which I might try, since I have nothing plugged into my network port :-) (I normally use the builtin trackpad thingy which is on psm0, which isn't irq 9 so that won't work, and trying to watch a DVD whilst wiggling the mouse might give me RSI). Have you tried the laptop with FreeBSD 4.X? I haven't tried mine, but it might do something differently that works (ie not use ACPI). Hmm, it'll probably panic... I should find a spare CD and try it.
