Back up just a few steps and be careful about dorking around in the
lowlevel part of the driver. You may need to review the differences
betwenn the storage classes. Try moving to an offboard host adapter like
a Promise Ultra33 or an Acard AEC6210UF.
These are modified ide-chipsets that behave like SCSI more closely.

It is obvious that your driver is not playing by the waitque rules.
Or something in RTL in combination in not servicing IDE is causing the
clash.

Surprized you did not lock up hard.

I do not know enough about your driver to answer the question.
Second I have not used RTL since I rewote part of it for something
personal back at 0.5a.
Again I suggest that anyone using RTL and an onboard IDE find one of the
two above mentioned cards and see if the services perform better.
