The driver is FreeBSD's standard "pcm" driver.  Its boot-time attach
messages identify the sound chip as follows:

pcm0: <Intel ICH3 (82801CA)> port 0x18c0-0x18ff,0x1c00-0x1cff irq 5 at device 31.5
on pci0
pcm0: <Analog Devices AD1881A AC97 Codec>

The pciconf utility says:

pcm0@pci0:31:5: class=0x040100 card=0x05081014 chip=0x24858086 rev=0x02 hdr=0x00
    vendor   = 'Intel Corporation'
    device   = '82801CA/CAM (ICH3-S/ICH3-M) AC'97 Audio Controller'
    class    = multimedia
    subclass = audio

Wow, that fixes it!  I never would have guessed that this problem had
anything to do with audio.

I'm a FreeBSD committer and might be able to help get our driver
fixed.  Do you know whether this particular sound chip works with Ogle
under Linux (without the OGLE_OSS_RESET_BUG work-around)?  If it does,
then maybe I can see what the Linux driver is doing differently when
it resets the chip.

Thanks very much for your help!
