[1.] the box with VIA Apollo Pro hangs up when using sound.
[2.] My linux box, Celeron 300A + VIA Apollo Pro + SoundBlaster16
sometimes hangs up, when I use the sound card. not always, but
it sometimes really hangs up only when using sound.
[3.] Keywords are ISA DMA, Soundcard, VIA Chipset, Apollo Pro, 82C596
[4.] kernel version is 2.2.11 and 2.2.12.
[5.] no oops messsage is avalable.
[6.] many sound programs, like sox/mpg123/snes9x... cause the problem.
[7.] environment is VIA chipset + ISA Soundcard
[additional info. with the patch.]
Hello, I'm enjoying linux but had some problem. And I fixed.
The Digest of the problem is this:
Apollo pro is not fixed the hardware bug described in
2.2.x-kernel-src/Documentation/sound/VIA-CHIPSET.
I checked kernel 2.2.12 source & document, and I found the document file,
and some comment in /usr/src/linux/drivers/pci/quirks.c.
I'm afraid the problem would cause my Linux box hang up,
and I made below patch. After patching the kernel,
my Linux box completely stable.
