Subject: 2.6.0-test6 alsa sound bug
Date: Mon, 29 Sep 2003 14:30:13 +0000 [thread overview]
Message-ID: <BAY7-F67hOY4l6Etx5300009dc0@hotmail.com> (raw)
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:
Unable to handle kernel paging request at virtual address d4971000
