IDE problem: 2.5.10 compiles but hangs during boot

IDE problem: 2.5.10 compiles but hangs during boot

[Mark Orr]

System:  Pentium 100, 16mb, Neptune II chipset w/ RZ1000 IDE
         WD Caviar 2540 (540mb) HD,   NEC-260 IDE CD
         
Linux 2.5.10 compiles but doesnt complete boot due to some IDE
errors.    Previous working kernel was 2.5.8-pre3.

relevant bits from the boot messages:
---
ide0: disable chipset read-ahead (buggy RZ1000/RZ1001)
ide1: disable chipset read-ahead (buggy RZ1000/RZ1001)
hda: WDC AC2540H, ATA disk drive
hdc: NEC CD-ROM DRIVE:260, ATAPI CD/DVD-ROM drive
ide0 at 0x1f0-0x1f7,0x3f6 on irq 14
ide: unexpected interrupt 1 15
ide1 at 0x170-0x177,0x376 on irq 15
hda: 1056384 sectors (541Mb) w/128Kib cache CHS=1048/16/63
Partition check:
  hda: [PTBL] [524/32/64] hda1 hda2 hda3

(...some network stuff, then it runs fsck)

remounting root device with read-write enabled.
hda: task_mulout_intr: status=0x65 { DriveReady DriveFault CorrectedError Error}
hda: task_mulout_intr: error=0x04 {DriveStatusError}
ide: unexpected interrupt 0 14
ide0: reset: success

...and there it stops.

My kernel configuration is default, except IDE CDROM is modularized.


After receiving this error, I went back and disabled CMD640 and 
Generic PCI IDE support - which has compiled and worked in the past,
but it doesnt compile with this kernel version:
