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 %&[EMAIL PROTECTED] 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.
