>Description:
On a 5.4 system with kde AND kmix running, if I run kldunload snd_ich twice the system freezes.
cat /dev/sndstat says:
FreeBSD Audio Driver (newpcm)
Installed devices:
pcm0: <Intel ICH6 (82801FB)> at io 0xdfebfe00, 0xdfebfd00 irq 23 bufsz 16384 kld snd_ich (1p/1r/0v channels duplex default)
I can post a full dmesg output if requested.
>How-To-Repeat:
Start kde, make sure you have kmix running. Run kldunload snd_ich
After this one you'll notice there are no /dev/dsp* entries, but the module isn't unloaded. Run again kldunload snd_ich again. Freeze
