Hi,
I get this error a lot of times, and I have tried looking at google too
without any solution(all I saw were postings of the problem). My System is
Gigabyte 7DXR. Kernel version is 2.6.8-1.521.
Has anybody found any solution to this problem?
Thanks and regards from
VJ

Have had this happen with some crappy hard drives I've run into over the
years.  Usually accompanies some loud clicking.  Chances are you are
trying to run in a DMA mode that the drive doesnt support, eg UDMA(100)
instead of UDMA(66) or the like.  Check your BIOS, if you have
configured your hard drives by hand you may have have a wrong setting.
Consider either letting your BIOS autodetect or passing values to the
kernel at boot time.  If this doesn't work I would like to see your
dmesg output, specifically where the kernel detects your drives and ide
controller(s).

Hi Jacob,
Thanks for reply. Hard disks are
hda : ST340016A
hdh : ST3160023A (was hdb)
and they are pretty new. Today morning I moved hdb (the second hard disk to prmise controller(i had it disabled first, but had to enable it today using a jumper on the mobo. Now hdb is hdh)


Partial output of dmesg is at the end
