Correction: your system is unstable in 2.1.85. Cause unknown.

Well.. try a non-SMP kernel then. I did receive other reports a few

After a unit reset, the hardware should no longer be "Busy".
Something other than the IDE software is causing this condition.

Yeah, try it without the IO_APIC support.
