Description of Problem:
On some hardware, the routine 'ide_reset()' simply tanks.
Version-Release number of selected component (if applicable):
< 100% - it fails on only one machine I have, but not on any others.
Steps to Reproduce:
It seems that some PC's generate an NMI when the IDE reset line is asserted :-(
The fix is to have this suppressed, at least when IDE reset is happaning.
