Hi,

re: SB16 and PAS16 problems

I have been running FreeBSD V2.1 installed from WC CDROM with an
Adaptec 2840 without issue for a month. (previously a 1542). I recently
bought a soundblaster card (Vibra16 based with three CD interfaces) to
use on the system. I built a kernel following the sound.doc and using 
LINT
config gile as an example and checking I have no IRQ conflicts. I use
high and low DMA. I also tried a PAS16 Studio with the same result.

Basically, I boot the kernel from a 4GB drive on the 2840, I see the 
2840
sense the devices on the bus, I see the sound devices configure and can
start Xwindows. I have no problems with the system which has a lot of
network activity UNTIL I try to play a sound. I have made sure I have 
MAKEDEV sb or pas16 and when run xanim on a .mov or .avi file I see the
image start and hear the FIRST few bars of the sound or music and then
the system hangs. This sometimes just freezes and I have to press reset
OR it reboots the PC from scratch.

MOST times I have to use the fixit floppy to fix the root partition 
which gets
screwed (eg some pty devices files die and some package DESC+ files
get deleted and SOMETIMES the root file system home block gets 
corrupted) AND also sometimes the .mov file (in another filesystem) 
which was only
being read AND it's directory gets creamed as well.

This means every iteration of testing the sound card(s) I have to fix up 
or
restore my filesystem(s)! I don't know why the .mov file gets written 
when 
it's playing.

I booted dos and used the manufacturers utils for the soundcards and all
works fine. (other system devices like 2840 would have been idle)

I am thinking that there may be an issue with voxware and the new 
aic777x
driver over DMA or some other resources.

My next test is to replace the AHA1540 and see if that works with the 
sound
cards.

I would appreciate hearing from anyone successfully running with an SB16
or PAS16 Spectrun/studio who uses an Adaptec 2840 and if possible a look
at sound_config.h and CONFIG files.

If anyone else is having the same problem, I would also like to hear 
(mainly to save my sanity!) and if you have a solution.

Many thanks.
