It appears drivers/scsi/libata-eh.c isn't getting built in the 2.6.17 
patch, seems to be missing in drivers/scsi/Makefile:

Yeap, right.  My bad.  I forgot to do 'quilt add' the Makefile.  The 
updated tarball is at

http://home-tj.org/files/libata-tj-stable/libata-tj-2.6.17-20060625-1.tar.bz2

Sorry about the trouble.

Seems to work great so far, only knit is that the kernel log does not 
print it out the NCQ bits as indicated in the README. queue_depth in 
sysfs do show proper values however, just a backport issue I guess.

It's actually a hiccup introduced by recent selective msg-enable in 
#upstream.  It will be resolved soon.

Thanks.
