[2.0.30] solid lock with SCSI, floppy and audio access

My 2.0.30 linux box got a solid lock yesterday when transfering data
from CD to floppy using tar while accessing /dev/audio at 16 bit, 44 kHz
stereo with a GF1 Gravis Ultrasound. I couldn't reproduce the problem
later, but I didn't try it so hard. The system load was around 30% at
the time, mixing four channel music and dumping it to the audio device.
