I've had hard lockups before disabling the 'quick boot'

Hmm. I have in my /etc/modprobe.conf
---------
alias char-major-116 snd
alias snd-card-0 snd-cs4236 
options snd-cs4236 isapnp=0 cport=0x538 port=0x530 sb_port=0x220 fm_port=0x388 irq=5 dma1=1 dma2=0
---------

The module is loaded with '/sbin/modprobe snd-card-0' in /etc/rc.local
and volume upped with gnome-volume control (volume,pcm,out-gain)


$ /sbin/lsmod  |grep snd
snd_cs4236             14916  0 
snd_opl3_lib            9344  1 snd_cs4236
snd_hwdep               6404  1 snd_opl3_lib
snd_cs4236_lib         18176  1 snd_cs4236
snd_mpu401_uart         7296  1 snd_cs4236
snd_rawmidi            21408  1 snd_mpu401_uart
snd_seq_device          6280  2 snd_opl3_lib,snd_rawmidi
snd_cs4231_lib         29572  2 snd_cs4236,snd_cs4236_lib
snd_pcm                82568  2 snd_cs4236_lib,snd_cs4231_lib
snd_timer              25092  3 snd_opl3_lib,snd_cs4231_lib,snd_pcm
snd                    43748  10 snd_cs4236,snd_opl3_lib,snd_hwdep,snd_cs4236_lib,snd_mpu401_uart,snd_rawmidi,snd_seq_device,snd_cs4231_lib,snd_pcm,snd_timer
soundcore               7520  1 snd
snd_page_alloc          8068  2 snd_cs4231_lib,snd_pcm


and 'mplayer file.mp3' works.

This is with FC2test 2.6 kernel.
