Okay,

I think that this a new problem with the latest sound driver which
most of you are not running. Somehow, whatever went into the kernel
lately has triggered a bug in the sound driver or maybe the 
bug was always there and it is now showing consistently in the sound driver.

The reason why I am blaming the sound driver is because I now I have 
vic up and running and typing all of this whereas in the past few hours
just a few seconds of playing with vic with video capture would crash my
system the minute that I tried to access the sound driver with vat.
vat-4.0a2 + my GUS PnP and no vic seems to be okay however if 
I use vic + vat my system crashes.This may correlate with a 
previously reported crash from Jordan with my latest sound driver and
his Gus MAX. None of this makes that much sense  at this point so I guess 
I have my weekend hacking cut out for me 8)
