just to clarify: does 2.4.7 hangs?
(for me it doesnt, but everything >= 2.4.8 does)
also as i already said, the sound isn`t clear:
there are little clicks here and there...
but i have an infinite trace(*). you - don`t.
(*) - in fact there are 3 traces.
first - quite short (1-1.5 screen)
second - 3-4 screens, and
third - infinite...

After i read in this list that some people do not experience
this problem in 2.4.7, I decided to give it a try.
2.4.7 crashes too, but behaves differently:

Humm.

Ok that actually sounds more like a locking bug.

Can you try one other thing.
Edit drivers/pci/quirks.c
find
int isa_dma_bridge_buggy; /* Exported */
and make it read
int isa_dma_bridge_buggy = 1;
recompile reboot and see if it helps

Unfortunately, it does not help. The machine rebooted
suddenly (i forgot to mention that: sometimes it reboots
too, but mostly it just hangs).
btw the system doesn't have a PCI bus, so its kernel
does not have PCI support enabled
(it's a SIS85C471B-based ISA/VLB motherboard)

Hello all,
A trace of the crashes would be helpful.
Regards,
Frank

unfortunately, i don't get any oops or panic messages.
There's nothing about it on the console, nothing in
logs either.
The box just freezes. No more ping/connection
replies, no more reaction to any keyboard input.
(this must be a very hard bug)
cheers

I have the same problems with an ALS007 card (in a 486 system).
The card is correctly recognized and set up by the PnP drivers.
The system freezes completely when using sound (no ping replies
anymore), and it's not a CPU/motherboard/RAM issue
(it compiles kernels without any problems), it occurs while
playing MP3's, while playing LxDoom ( now i have an excuse
to play Doom, testing the Linux sound drivers ;) ).
The time after which it crashes is variable, sometimes it crashes
immediately, sometimes it crashes after 5 minutes.
Sometimes, it also stalls a few times before finally crashing.
Having persistant DMA buffers enabled/disabled doesn't change
anything (the machine has 16MB of RAM), and the problem occurs
both when using modules or compiled-in drivers.
Both 2.4.8 and 2.4.9 have this problem (these are the ones I tried).
Btw on 2.2.x i get DMA (output) timeout errors (and broken sound).
There is also another "issue":
the ISAPnP code calls "CMI8330 quirk". As i have no such
card, i thought this was related to the problem. After
commenting it out in quirks.c and recompiling, the quirk
was not called anymore, but it didn't solve the problem.
greets
