recompile for 386 code, kernel and driver.
The Seagate IDE drive is marginal at the timing and signal gating
requirements of 586 code and often locks up. So do MOST WDs,
though some of them will work without the Xxx parm and often run
close to the UDMA66 speed required.
Read kernel traffic in February to learn why. It has to do with
the fact that drive and chipset mfgrs are assuming timing for 386
code instead of the "official" specs for the interface, and 586
code timing is tighter, hence reflections on signal gating lines
that should NOT be there are being observed.
IBMs, Maxtors, and Quantums in the same position on the same
board seem to work just fine.
