Is the hardware set up properly as in, are the cables connected correctly and are the master/slave/cable-select jumpers on the hard drivers in the correct places? This looks like a problem where the chipset detects devices on the two ends of the flatcable one way, but the drives themselves report the devices the other way round (because of the jumper settings).

Bios have detected well drives, that are 'on cable select' hda,hdb with 80 pin cable and 'master only' for hdc with 80 pin cable too. i found that related info: https://bugs.launchpad.net/ubuntu/+source/linux-source-2.6.20/+bug/119730 http://osdir.com/ml/ide/2005-03/msg00064.html Hope it helps Have you tested with gentoo-sources-2.6.26-r1 or the latest development kernel (git-sources).

(In reply to comment #4) > Have you tested with gentoo-sources-2.6.26-r1 or the latest development kernel > (git-sources). > Tested with kernel-2.6.25-gentoo-r6, kernel-2.6.26-gentoo-r1 and (vanilla) kernel-2.6.26.1. This bug is upstream. All kernel showing: hda: cannot use LBA48 DMA - PIO mode will be used for accessing sectors > 268435456 hda: 488397168 sectors (250059 MB) w/8192KiB Cache, CHS=30401/255/63 hda: cache flushes supported hda: hda1 hda2 hda3 hda4 hdc: max request size: 128KiB hdc: cannot use LBA48 DMA - PIO mode will be used for accessing sectors > 268435456 hdc: 488397168 sectors (250059 MB) w/8192KiB Cache, CHS=30401/255/63 First time I fpund a kernel issue. Please what I have to do now? Resolved upstream |
