2.5.65-ac2 -- hda/ide trouble on ICH4

[Dominik Brodowski]

Hi Alan,

unfortunately 2.5.65-ac2 does not boot:

ICH4: IDE controller at PCI slot 00:1f.1
ICH4: chipset revision 1
ICH4: not 100% native mode: will probe irqs later
    ide0: BM-DMA at 0xf000-0xf007, BIOS settings: hda:DMA, hdb:pio
...
hda: ICH35L080AVVA07-0, ATA DISK driver
ide0 at 0x1f0-0x1f7,0x3f6 on irq 14
...
hda: host protected area => 1
hda: 160836480 sectors (82348 MB) w/1863KiB Cache, CHS=159560/16/63, UDMA(100)
 hda: [PTBL] [10011/255/63] hda1 hda2 hda3 hda4 < hda5 hda6 hda7 hda8 hda9 >

and *deadlock*...

in plain 2.5.65 I was seeing strange error messages like:

Mar 19 20:29:55 mondschein kernel: hda: dma_timer_expiry: dma status == 0x24
Mar 19 20:29:55 mondschein kernel: hda: lost interrupt
Mar 19 20:29:55 mondschein kernel: hda: dma_intr: bad DMA status (dma_stat=30)
Mar 19 20:29:55 mondschein kernel: hda: dma_intr: status=0x52 { DriveReady SeekComplete Index }
Mar 19 20:29:55 mondschein kernel:

which are not repeatable when I switch back to 2.5.62.
