Hello Allen,

I'm reviewing this bug as part of the kernel bug triage project, an attempt to
isolate current bugs in the fedora kernel.

http://fedoraproject.org/wiki/KernelBugTriage

I am CC'ing myself to this bug and will try and assist you in resolving it if I can.

There hasn't been much activity on this bug for a while. Could you tell me if
you are still having problems with the latest kernel?

If the problem no longer exists then please close this bug or I'll do so in a
few days if there is no additional information lodged.

Cheers
Chris

Okay, thanks for the update Allen. I'm re-assigning to the relevant maintainer
who may be able to shed some more light on this.

Cheers

Comment 6 Alan Cox 2007-09-19 09:57:56 UTC 
Added to the list of device and versions which seem to have faulty firmware for
NCQ. Please check if newer firmware is available. In the mean time I'll push
this one into the main tree so that NCQ is blacklisted for the drive in question.

The kernel will actually disable NCQ use on the drive after a few attempts when
it sees this problem anyway.
