the new nforce2 ide drivers in the kernel seem
to have a problem - my drive will only
go to udma33 (tried nforce2 and amd viper in
different recent kernels):

hda: 156301488 sectors (80026 MB) w/2048KiB Cache, CHS=9729/255/63, UDMA(33)

DMA modes: mdma0 mdma1 mdma2 udma0 udma1 *udma2 udma3 udma4 udma5

Timing buffered disk reads: 64 MB in 3.70 seconds = 17.30 MB/sec


Yet, with the stock RedHat 7.3 kernel I can get
full performance:

DMA modes: mdma0 mdma1 mdma2 udma0 udma1 udma2 udma3 udma4 *udma5

Timing buffered disk reads: 64 MB in 1.59 seconds = 40.25 MB/sec

This is on a shuttle sn41g2.
