Linux 2.6.6 "IDE cache-flush at shutdown fixes"

Good day.

The 2.6.6-rc3 -> 2.6.6-final changes to ide-disk.c unfortunately make my machine complain loudly both at boot and reboot:

Uniform Multi-Platform E-IDE driver Revision: 7.00alpha2
ide: Assuming 33MHz system bus speed for PIO modes; override with idebus=xx
AMD7409: IDE controller at PCI slot 0000:00:07.1
AMD7409: chipset revision 7
AMD7409: not 100% native mode: will probe irqs later
AMD7409: 0000:00:07.1 (rev 07) UDMA66 controller
ide0: BM-DMA at 0xf000-0xf007, BIOS settings: hda:DMA, hdb:pio
ide1: BM-DMA at 0xf008-0xf00f, BIOS settings: hdc:DMA, hdd:pio
hda: Maxtor 6Y120P0, ATA DISK drive
ide0 at 0x1f0-0x1f7,0x3f6 on irq 14
ide1 at 0x170-0x177,0x376 on irq 15
hda: max request size: 128KiB
hda: 240121728 sectors (122942 MB) w/7936KiB Cache, CHS=65535/16/63, UDMA(66)
hda: hda1 < hda5 hda6 hda7 hda8 hda9 hda10 hda11 hda12 hda13 > hda2 hda3 hda4
hda2: <bsd: hda14 hda15 hda16 hda17 hda18 >
hda4: <minix: hda19 hda20 >
hda: task_no_data_intr: status=0x51 { DriveReady SeekComplete Error }
hda: task_no_data_intr: error=0x04 { DriveStatusError }
hda: Write Cache FAILED Flushing!

The disk, 6Y120P0, is a new-ish Maxtor "DiamondMax Plus 9", 120G, 8M cache. Controller is an AMD756. Same complaints on reboot. Reverting the rc3->final changes to ide-disk.c fixes/supresses them again.
