SubjectRe: IDE tape and SMP

This is a real bug folks and I am looking into the issue.

ide-tape: ht0: I/O error, pc = a, key = 9, asc = 3, ascq = c
tar: Cannot write to /dev/ht0: I/O error
hdd: irq timeout: status=0xd0 { Busy }
hdd: ATAPI reset complete
ide-tape: Couldn't write a filemark

ide-tape: ht0: DSC timeout
hdd: ATAPI reset complete
ide-tape: ht0: I/O error, pc = 1, key = 2, asc = 4, ascq = 1

I am using a SM P6DNF and 124 SMP faults.........
I forgot the tast kernel that there was not an error under SMP, but the
hunt is on..................release the hounds..........
