Hello,

After upgrading to 2.6.19-rc6 and enabling experimental support of 
pata_via noticed that my hdd was downgraded to UDMA/33:

Before (2.6.18-rc & via82cxxx):

Uniform Multi-Platform E-IDE driver Revision: 7.00alpha2
ide: Assuming 33MHz system bus speed for PIO modes; override withidebus=xx
VP_IDE: IDE controller at PCI slot 0000:00:07.1

Now (2.6.16-rc6 & pata_via):

         DMA: mdma0 mdma1 mdma2 udma0 udma1 *udma2 udma3 udma4

BTW: is it possible to do something with this annoying long delay with 
the "port is slow to respond, please be patient" message? :)

Best regards,

Looks like a cable detect error.

This is a known bug in the libata core at the moment

No, but it does appear to be a bug. Can you send me an lspci -vvxxx

Oh, indeed. Forcing ATA_CBL_PATA80 brings back expected UDMA66 speed.
