I take it kernels < 2.6.23 are known to be functional? If so, a git bisect should be really easy if you're a git user _and_ the breakage is in drivers/ata/sata_via.c, there are only two meaningful commits involved. homer:..git/linux-2.6 # git bisect start -- drivers/ata/sata_via.c homer:..git/linux-2.6 # git bisect good v2.6.22 homer:..git/linux-2.6 # git bisect bad v2.6.23 Bisecting: 2 revisions left to test after this A full bisection would take quite a few more builds. (I haven't noticed anybody else reporting similar troubles, and quite a lot of time has passed since 2.6.22 was released.. that makes me suspicious of your hardware) Maybe you should post again, and add cc's to linux-ide@...r.kernel.org and linux-scsi@...r.kernel.org, perhaps someone there can give you a better idea. > A simple test with a DVD RAM and dd instead of growisofs > > dd if=/dev/zero of=/dev/srX bs=1024k count=10 > > and a readback afterwards > > dd if=/dev/srX of=imageX.bin bs=1024k count=10 > > gives me an all zero file from the IDE drive but a file > full of probably scsi commands for the SATA drive and looks like > > 00000000 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 |................| > * > 00020000 2a 00 00 00 00 40 00 00 40 00 00 00 00 40 00 00 |*....@..@....@..| > 00020010 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 |................| > * > 00040000 2a 00 00 00 00 80 00 00 40 00 00 00 00 80 00 00 |*.......@.......| > 00040010 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 |................| > * > 00060000 2a 00 00 00 00 c0 00 00 02 00 00 00 00 c0 00 00 |*...............| > 00060010 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 |................| > * > 00061010 00 00 00 00 00 00 00 00 2a 00 00 00 00 c2 00 00 |........*.......| > 00061020 40 00 00 00 00 c2 00 00 00 00 00 00 00 00 00 00 |@...............| > 00061030 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 |................| > * > 00081010 00 00 00 00 00 00 00 00 2a 00 00 00 01 02 00 00 |........*.......| > 00081020 40 00 00 00 01 02 00 00 00 00 00 00 00 00 00 00 |@...............| > 00081030 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 |................| > * > 000a1010 00 00 00 00 00 00 00 00 2a 00 00 00 01 42 00 00 |........*....B..| > 000a1020 40 00 00 00 01 42 00 00 00 00 00 00 00 00 00 00 |@....B..........| > 000a1030 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 |................| > * > 000c1010 00 00 00 00 00 00 00 00 2a 00 00 00 01 82 00 00 |........*.......| > 000c1020 40 00 00 00 01 82 00 00 00 00 00 00 00 00 00 00 |@...............| > 000c1030 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 |................| > > I really need some hints to make the SATA drive usable, please. > > best Regards > Gerold > > > uname -a > Linux blaubaer 2.6.24.2 #4 Sun Feb 24 21:50:21 CET 2008 x86_64 AMD Athlon(tm) > 64 Processor 3400+ AuthenticAMD GNU/Linux > > lspvi -v > > 00:0f.0 RAID bus controller: VIA Technologies, Inc.
