Spooky dmesg messages

[L29Ah]

I receive the following stuff pretty frequently. I got a kernel panic when an application tried to play several sounds simultaneously once, but that might be irrelevant.

Code: Select all

Interesting.. if there's an issue it's probably vmix related. Can you provide info about your kernel/general setup ('uname -a', 'lsmod', 'lspci -vnn', 'ossinfo -v3')? Also, you may try to rebuild OSS, maybe using --config-vmix=FIXEDPOINT.

Did that, didn't help. When i launch my IM client and it spams with sound notifications, i get the same dmesg message.
