Problem noticed by Joe Zbiciak, see http://kerneltrap.org/node/8252 for details. On CSB6 the driver is using BIOS settings and not programming DMA/PIO timings itself. However the logic was completely broken and resulted in wrong timings being silently allowed (instead of being corrected by the driver). This bug would explain some data corruption/timeout issues with Serverworks MegaIDE in RAID mode that Alan Cox has fixed recently with: http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commitdiff;h=2074a106f52b6371885afbd714e929d60d0e3f64 For 2.6.23 we may be better off with completely switching the driver to always programming timings (libata pata_serverworks.c driver is doing things this way and there were no problems reported so far) but for 2.6.22 lets fix the bug in the simplest and the least intrusive way.
