Hmmm, that could be the issue. I remember (and even have code IF-ed
out) to do ATA sans interrupt and it would run into problems. I found
that waiting for the interrupt to hit fixed the instability. Granted,
this was in simple x86 code, but if I didn't have to put the ISR code
in, I wouldn't have done it--as it it makes things a bit more complicated.
FWIW, I can pass you the code I was using circa 1999. It might shed
some illumination.
