I got a crash and system hang in my system initialization scripts.
My startup scripts essentially do (this is the short version):
modprobe snd
modprobe sound-slot-0
modprobe sound-slot-1
/usr/sbin/alsactl restore >/dev/null 2>&1
I'm not sure if the hang was in one of the modprobes or
when alsactl was run. /etc/modprobe.conf contains:
alias sound-slot-0 snd-intel8x0
alias sound-slot-1 snd-ice1712
