some days ago I mailed to the list, about an oops that occured, when I
recorded some stuff with my CS4232-soundcard (compiled as modules).
I first compiled with egcs1.1 and -mpentium & -march=pentium settings
on.
THEN, to be sure, I recompiled the kernel and modules with gcc 2.7.2.3.
The problem still exists!
I may record one time, successfully, then, when recording the second
time, it oopses!
Now, below there is an _interesting_ (?) result: Compiling the sound
driver
into the kernel does NOT trigger the problem!!!
BUT: By mistake, a script of mine _did_ insmod sound.o and soundcore.o
it
happened again, I donīt know, whether all those traces where of any use,
but I think the last one IS !?

My next step will be to try, if it works with sound compiled in.
If You do need any further info, just drop me a line and I see, what I
can do.
