Comment 12 for bug 147858

As this seems more active, I crosspost from here: https://bugs.launchpad.net/ubuntu/+source/linux-source-2.6.22/+bug/137470/comments/26

Hi all,

I need to disappoint some of you:
Dell Vostro 1700 with a Seagate ST980813ASG

Suggested fix in https://wiki.ubuntu.com/InstallingUbuntuOnADellVostro1700 was to turn off NCQ by piping "1" into /sys/block/sda/device/queue_depth

I did this.

Also I upgraded to 2.6.24 as explained here: http://axebase.net/blog/?p=178 (uses a script "hardy.py")
> uname -a
> Linux vostroxx 2.6.24-8-generic #1 SMP Thu Feb 14 20:40:45 UTC 2008 i686 GNU/Linux

The problem first occurred to be gone but after about half an hour of working it appeared again (see below).

What should I do now? I remember to see a patch where NCQ was turned off for ST980813AS in the kernel 2.6.24. But I do have a "ST980813ASG" (note the appended "G"). But then, I have turned off NCQ anyway by piping "1" into /sys/block/sda/device/queue_depth, didn't I?

Do I (and others) experience a wholly different problem here?
