I had an oops in 2.1.100pre1 just now.

I tried this both as root and as a normal user.

It's propably not a serious thing, but oopsing isn't the proper
behaviour, or what?

Here we go:

First load the sound drivers. Then view /proc/sound in Midnight
Now unload the sound drivers. When I "unview" /proc/sound I get an oops.

Kernel compiled with egcs-1.0.2, Redhat-5.0 system, binutils-,
AMD K6-200 with the famous bug.

Output of ksymoops attached.
