On 2.6.26.5 + the pending stable queue applied, this patch results in lots 
of noise in my syslog (full gzipped dmesg with and without this patch 
attached):

ata4: EH complete
ata5: EH pending after 5 tries, giving up
ata5: EH complete
ata6: EH pending after 5 tries, giving up
ata6: EH complete
ata5: EH pending after 5 tries, giving up
ata5: EH complete
ata6: EH pending after 5 tries, giving up
ata6: EH complete

reverting just this patch fixes the issue again.

This triggers reproducably for me on different nforce3 and nforce4 systems

This patch has been removed from the stable queue, so it shouldn't be an

It's currently a mess.  Please take a look at the following message for
the whole story.

  http://article.gmane.org/gmane.linux.ide/34942

It's interesting how they fixed hardreset of the chipset step-by-step. :-(

Thanks.

Ick, you are right, what a mess.

Do you want that patch in 2.6.26-stable now?  Or just don't worry about
it?

2.6.26-stable should be fixed but given the series of breakages I
wanna be a bit cautious before proceeding.  Just give me a few more
days so that I can confirm the posted patch fixes the problem for both
generic and nf2/3 flavors.  I'll forward the final patch against
-stable to you then.

Thanks.

Yes, you're right. I missed it being removed from queue-2.6.26 a few hours 
before I actually sent the mail, sorry for the noise.
