As detailed in the following link I have to disable pciide and set my BIOS to use SATA drives in 'compatible' mode in order to use my HP2133 netbook with the cheap 4GB SSD it came with:
http://www.nabble.com/Re%3A-Interrupt-problems-with-recent-snapshot-p20160942.html I looked into the problem and discovered that my drive only supports Ultra-DMA mode 4. The pciide/wdc code forces various PIO/DMA settings (including UDMA5) when it detects a SATA drive in 'native' mode and dispenses with any autodetection. The following patch just removes the forced settings and lets the autodetection run. My drive is detected properly with my BIOS set to use native SATA and runs at a more acceptable speed. Presumably someone added that code because some drives don't work with autodetection so I doubt this patch can be applied to 4.6-beta without more widespread testing.
