Linux 2.6.20-git - PATA UDMA/100 configured as UDMA/33

["Fabio Comolli" <fabio.comolli@gmail.com>]

Hi.
I see a regression in latest -git (2.6.20-g91aa6931). My PATA hard
disk is not correctly configured:

---------------------------------------------------------------------------
libata version 2.10 loaded.
ata_piix 0000:00:1f.1: version 2.00ac7
ata1: PATA max UDMA/100 cmd 0x000101f0 ctl 0x000103f6 bmdma 0x000118c0 irq 14
ata2: PATA max UDMA/100 cmd 0x00010170 ctl 0x00010376 bmdma 0x000118c8 irq 15
scsi0 : ata_piix
ata1.00: ATA-6: TOSHIBA MK8025GAS, KA024A, max UDMA/100
ata1.00: 156301488 sectors, multi 16: LBA
ata1.01: ATAPI, max MWDMA2
ata1.00: configured for UDMA/33
ata1.01: configured for MWDMA2
scsi1 : ata_piix
ata2: port disabled. ignoring.
scsi 0:0:0:0: Direct-Access     ATA      TOSHIBA MK8025GA KA02 PQ: 0 ANSI: 5
-----------------------------------------------------------------------------

Linux-2.6.20 correctly configures the drive as UDMA/100.

Please let me know if you need more details.
Regards,
Fabio
