2.2.21pre2 VIA IDE lockup during boot

[Jani Forssell]

We have a Abit KT7 raid with all the drives attached to the onboard VIA IDE
controller. It gets stuck during boot with 2.2.21pre2, but works with
2.4.18pre2. Here's a bit of the boot sequence:
[snip]
hda: Samsung SV8004H, ATA DISK drive
hdb: CDROM 52X/AKH, ATAPI CDROM drive
hdc:  Samsung SV8004H, ATA DISK drive
ide0: ...
ide1: ...
[stops here]

And it doesn't get past this point. SysRq->ShowPc shows this:

EIP 0010:[<c0109b1c>] EFLAGS: 00000202
EAX: 000001C0 EBX: 0000000e ECX: 0000000e EDX: c024c000
ESI: 0000000e EDI: c026f2e0 EBP: c026f2a0 DS: 0018 ES: 0018
CR0: 8005003b CR2: 00000000 CR3: 00101000

According to System.map, c0109b1c would be in disable_irq().

c0109ab8 T disable_irq_nosync
c0109af8 T disable_irq
c0109b24 T enable_irq

Some combinations do work, however:

-Both HDDs on channel 0 (hda, hdb) (works)
-Both HDDs on channel 0 (hda, hdb) and CDROM on channel 1 (hdc) (works)
-Both HDDs on different channels (hda, hdc) (works)
