Does the drive work without the patch? If yes, please send me 'hdparm -i /edv/hdc', 'lspci -vvxxx' for both the cases with and without the patch, and 'cat /proc/ide/via' for the case with the patch. I'll check if all the timings programmed really are correct.
Maybe we have a candidate for drive PIO timing black list.
