HMMM I seemed to have lost the 1st of the thread, 2 cents worth .. what 
ya pay for ...

I might be supect of the m/b IDE channels (personally had lots of 
failures) - SMART drives that are not configured as SMART (sorry, I 
always use Intel, AMD...?) enableing in bios and kernel or mod might 
give clues.  I, also, think that there must be an IRQ conflict, IRQ 
unanswered, or same ilk.

You could test by  swapping drives, swapping m/b's.  What sizes are your 
disks?  What RAM do you use,, I do have a plethora of hwde I could loan.
