DMA errors, then I/O errors, on 2.6.16

DMA errors, then I/O errors, on 2.6.16

[Andrew Moise]

  Running 2.6.16 (and some earlier 2.6 kernels as well), I get
occasional DMA failures, which are always followed by the disk not
working at all (any request leads to an I/O error).  The log and whatnot
follows.  Can anyone tell me what the source of this trouble might be
(disk, controller, cable, software)?
  Please CC replies to me, as I'm not on the list.  Thanks.

Hi!

I am just a single user, but i have get this too earlier.

If it is a WD hdd, try to use master AND slave on the same cable, or try to
set "cable select" setting on hdd!

This works for me! ;-)

(Only WD made this for me, and only when it is a single master drive.)

Cheers,

Janos

Have you tried running 'badblocks /dev/hda' under a kernel that is
believe to be working?  That looks more like a drive trying to fail
due to hardware causes than a software problem.....

  Sadly, it's a Maxtor drive, already set to cable select.  When I
opened the case to check the jumper, I noticed that the drive is very
hot; I tried improving the airflow to see if it's caused by the drive
overheating.

this tends to be a disk dying.. better run smartctl to check it out...
