For testing, first try without X but just use Linux console, so that
you have a better chance to see Oops messages.  It's pretty important
to see whether it's an Oops or a panic.  Also, double-check whether
you really installed the corrected drivers.  Often it's missing in the
right place by stupid reasons.

For first tests, don't use any sound server.  Try with aplay like:
	% aplay -Dhw foo.wav
Try first 96kHz samples, 48kHz samples, and then others.
