I have a 666MHz Via Epia-ML motherboard (using a Via Eden, I think). I am booting it from a CompactFlash card attached by an IDE-CF adapter. Everything works fine under 2.6.18. Under 2.6.19, 2.6.19.1 and 2.6.20-rc1, the master device on ide0 is not seen. With all of the kernels, good and bad, I see approximately the following two lines after the via82cxxx module loads: ide0: BM-DMA at 0xdc00-dc07, BIOS settings:hda: DMA, hdb: pio ide0: BM-DMA at 0xdc08-dc0f, BIOS settings:hdc: pio, hdd: pio Under 2.6.18 and before, I also a line like this shortly thereafter, which is absent under 2.6.19.1 and 2.6.20-rc1. hda: TRANSCEND, CFA disk drive After that, the ide-disk module sees hda as a hard disk under 2.6.18, and does not see the device under 2.6.19 and later. 2.6.19 and later see the hard disk if I have it connected to the ide1 cable (that is, as hdc) instead of ide0. In that case, I have tried booting with the flash disk as hdc and a CD-ROM as hda, and the result is that the CD-ROM in hda is not seen. I have another computer, with a much faster CPU, that also uses the via82cxxx module for IDE, using the same kernel and module binaries, which does see a flash card attached as ide0 master under all of these kernel versions. I know that there is plenty more that I can do to narrow this problem myself, such as narrowing the problem to intermediate kernel versions, trying libata + via_pata instead, and other things, but I am reporting it now in case anyone else is already aware of the problem, as I've already been fiddling with it on and off for a few days. If nobody has anything to add about this, then I'll post follow-ups as a narrow or resolve it.
