Mr. Brown,
I just recently got 2.6.0-test5-bk10 working on my Gateway 600S laptop, which
has an ESS Allegro Maestro3 chip. Right now I'm using the maestro3 OSS driver
under 2.4.22-ac2 without problems, but when I boot to 2.6.0-test5-bk10 and try
to use the driver (i.e. open /dev/dsp using the Mozilla Shockwave plugin), I
get the following Oopses:
Unable to handle kernel NULL pointer dereference at virtual address 00000188
printing eip:

The driver detects my chip like this (the driver itself is compiled as a
module):
maestro3: version 1.23 built at 18:55:27 Sep 23 2003

ac97_codec: AC97 Audio codec, id: 0x4583:0x8308 (ESS Allegro ES1988)
And under 2.6, lspci -vv says this:

Should I try the ALSA drivers next? Or is this a bug fixed elsewhere? (i.e.
2.6.0-test5-mm4)
TIA

Mr. Brown,
UPDATE: The same problem appears on 2.6.0-test5-bk11. It appears to be a bug in
the /dev/dsp code. I tried running mplayer under test5-bk10 and test5-bk11, and
these are the Oopses that mplayer reports under test5-bk11:

Should I just try the ALSA drivers w/OSS emulation? I know I should be using
them but Red Hat 9 is quite involved to get complete ALSAness working on it....
