Ata2: port failed to respond (30 secs) and ata2: SRST failed

Question

Hello,
I just upgraded from 2.6.17.13-3 to 2.6.18-4 (testing) and when I am booting I hang temporarily with an ATA problem.  Here is a snippet from dmesg...
ata1: SATA max UDMA/133 cmd 0xFE00 ctl 0xFE12 bmdma 0xFEA0 irq 18
ata2: SATA max UDMA/133 cmd 0xFE20 ctl 0xFE32 bmdma 0xFEA8 irq 18
scsi0 : ata_piix
ata1.00: ATA-6, max UDMA/133, 156250000 sectors: LBA48
ata1.00: ata1: dev 0 multi count 8
ata1.01: ATA-7, max UDMA/133, 312581808 sectors: LBA48
ata1.01: ata1: dev 1 multi count 8
ata1.00: configured for UDMA/133
ata1.01: configured for UDMA/133
scsi1 : ata_piix
ata2: port is slow to respond, please be patient
ata2: port failed to respond (30 secs)
ata2: SRST failed (status 0xFF)
ata2: SRST failed (err_mask=0x100)
ata2: softreset failed, retrying in 5 secs
ata2: SRST failed (status 0xFF)
ata2: SRST failed (err_mask=0x100)
ata2: softreset failed, retrying in 5 secs
ata2: SRST failed (status 0xFF)
ata2: SRST failed (err_mask=0x100)
ata2: reset failed, giving up

Vendor: ATA Model: WDC WD1600JS-00M Rev: 02.0

Any ideas?  Thanks.

I read that LKM thing and it seems they found a patch if you continue reading, against 2.6.18.  Don't know if anyone wants to try it out, but here:
