| |
Beginning with 2.6.5-rc1 I had an oops with panic on reboot on one specific computer. Since I couldn't capture it, I ignored it for some time but it's still present in yesterdays 2.6.6-rc1+BK snapshot. So I took a snapshot of the oops with digital camera and it is available at http://www.cs.ut.ee/~mroos/sound-oops.jpg for some time.
It only happens when I have used PCM sound after boot. Just booting the machine up, logging into KDE (it restores mixer settings), playing TV with tvtime (also uses mixer) and rebooting shows no problem. As soon as I play one file with sound using mplayer, the reboot hangs with this oops & panic.
I am using alsa drivers with snd_ens1371 (primary card, tested with mplayer) and snd_via82xx (secondary card) drivers. snd_pcm_oss and snd_mixer_oss are also loaded. snd_via82xx depends on snd_mpu401_uart so this is also loaded. I don use midi uart, at least not knowingly.
