I have i810 motherboard with onboard sound card. When I play some sound file with play for the first time after the boot, the kernel module snd_pcm_oss crashes. The file is played normally. It happens when closing the /dev/dsp0 After that the /dev/dsp0 can not be opened. After that any program that tries to opne /dev/dsp0 sleeps on open(/dev/dsp0,...). Here is the Oops:

Here is the out from lsmod: Module Size Used by iptable_filter 2464 1 ip_tables 14624 1 iptable_filter snd_pcm_oss 48324 0 snd_mixer_oss 14896 1 snd_pcm_oss snd_intel8x0 20772 0 snd_ac97_codec 46212 1 snd_intel8x0 snd_pcm 80224 2 snd_pcm_oss,snd_intel8x0 snd_timer 19872 1 snd_pcm snd_page_alloc 9092 2 snd_intel8x0,snd_pcm snd_mpu401_uart 5392 1 snd_intel8x0 snd_rawmidi 18816 1 snd_mpu401_uart snd_seq_device 6452 1 snd_rawmidi snd 40676 9 snd_pcm_oss,snd_mixer_oss,snd_intel8x0,snd_ac97_codec,snd_pcm,snd_timer,snd_mpu401_uart,snd_rawmidi,snd_seq_device
After the crash snd_pcm_oss and snd_intel8x0 are used.
