Maybe this can help. A few days ago, the cmos battery died (at power
up, the bios was asking me for date and time). I bought a new one from
ebay and installed it. Now the computer remembered the date and time,
and everything was back to normal, except that the %&*@# sound system
again didn't work. The driver got into a loop when loaded, it was not
possible to unload it or kill it and cpu utilization went to 100%.
Luckily I took good notes when I got it to work. The devices got
disabled when the cmos battery died. Doing this re-enabled them:
# echo 'activate' > /sys/devices/pnp0/00:06/resources
# echo 'activate' > /sys/devices/pnp0/00:07/resources
After that, the sound driver (snd-cs4231) loads just fine and sound is
back to normal.
# cat /sys/devices/pnp0/00:06/resources
state = active
io 0x538-0x53f
# cat /sys/devices/pnp0/00:07/resources
state = active
io 0x388-0x38b
io 0x220-0x233
io 0x530-0x537
irq 5
dma 1
dma 0
Before the re-activation, "disabled" was returned.
