Okay, I've finally had the time to look more carefully into this problem. I started sound playing and then started writing to the floppy continuously in each case to see if I could get the machine to freeze. Here are the results from various kernels.
2.0.35 - didn't lock in over an hour of writes (repeated twice) 2.1.121 UP - locked within ten minutes of beginning writing to the floppy 2.1.122 SMP - locked twice (once in about two minutes; the next within six)
The only anomaly I noticed under 2.0.35 was that the sound seemed to stutter some while writing to the floppy.
This leads me to believe that it is NOT, at least not completely, a hardware problem. Instead, it seems to be a problem within the kernel itself. If it is a hardware based problem, then the 2.0 series seems to have some sort of work-around for it. Even with this being the case, the best workaround may be to just stop sound when writing to the floppy device. I would implement this though I have no clue where to start with doing this :) If anyone would give me some suggestions on where to start, I'd be glad to work on it; if someone would instead like to try and patch it, I'll test any patches.
My system is a Dell P200 MMX with 64 megs of RAM and an on-motherboard Vibra 16 (Sound Blaster). Any additional information can be provided upon request.
