>Description:
              VIA 8285 sound card works in an erratic fashion; at times reboot brings it back; was unproblematic under FreeBSD 5.4; kernel compiled with 

device sound
device "snd_via82C686"

which is unchanged from the working 5.4 configuration

output of env is

This is a snippet from dmesg

pcm0: <VIA VT82C686A> port 0x1000-0x10ff,0x1c54-0x1c57,0x1c50-0x1c53 irq 5 at device 7.5 on pci0
pcm0: [GIANT-LOCKED]
pcm0: <Analog Devices AD1881A AC97 Codec>
pci0: <simple comms> at device 7.6 (no driver attached)

it appears like this idependent of whether the sound card worked or not

I am not sure if I am doing something wrong or there is actually a problem in the way the 6.0 kernel handels that sound card or its own boot sequence

>How-To-Repeat:
              The problem is erratic, some boots bring up the sound card and it is then accessible to applications, at other times cat /dev/sndstat does not show a configured sound card and there is no /dev/dsp.
>Fix:
              none
