Hi.
For a month or two I've been experiencing some trouble with the VIA AC97
sound card attached to my motherboard.. The machine in question is
running smoothly and playing mp3s and movies and then all of a sudden
(usually when it has been on for about 10 days or so) this will flood
dmesg and /var/log/messages:
Mar 22 16:22:43 eurisco kernel: Assertion failed! chan->is_active ==
sg_active(chan->iobase),via82cxxx_audio.c,via_chan_maybe_start,line=1388
Any ideas?
.config and lspci output attached.
Thanks.

I'm always seeing this too in my box (which is running 2.6.0).
Jeff, Alan, the assert seem erroneous?
/**
* via_chan_maybe_start - Initiate audio hardware DMA operation
* @chan: Channel whose DMA is to be started
*
* Initiate DMA operation, if the DMA engine for the given
* channel @chan is not already active.
*/
static inline void via_chan_maybe_start (struct via_channel *chan)
{
assert (chan->is_active == sg_active(chan->iobase));
and
static int sg_active (long iobase)
{
u8 tmp = inb (iobase + VIA_PCM_STATUS);
if ((tmp & VIA_SGD_STOPPED) || (tmp & VIA_SGD_PAUSED)) {
printk(KERN_WARNING "via82cxxx warning: SG stopped or paused\n");
return 0;
}
if (tmp & VIA_SGD_ACTIVE)
return 1;
return 0;
}
The driver works normally, even with the assert happening:
