Tejun's rework of cable detection code which fixes the problem has been just applied into "upstream" (not "upstream-fixes") so it is destined for 2.6.25 (I wasn't on cc: BTW) and since I got no feedback on my patch (below) which also happens to fix the regression, was acked by Alan, tested by Thomas and has been in -mm for 3 weeks now I assume that everybody is happy with it (Jeff/Tejun: you were also on cc: when the patch was merged into -mm)... Linus, please apply. [PATCH] pata_amd/pata_via: de-couple programming of PIO/MWDMA and UDMA timings * Don't program UDMA timings when programming PIO or MWDMA modes. This has also a nice side-effect of fixing regression added by commit 681c80b5d96076f447e8101ac4325c82d8dce508 ("libata: correct handling of SRST reset sequences") (->set_piomode method for PIO0 is called before ->cable_detect method which checks UDMA timings to get the cable type). * Bump driver version.
