<grin> that's what everyone says!

Just to be clear. This problem is where my system won't resume after s2d unless 
I umount my xfs over raid6 filesystem.

Yes

Yes, after I posted I realised that Andrews patch fixed the compile failure 
:)

git reset --hard 9666f4009c22f6520ac3fb8a19c9e32ab973e828

So now this compiles but it does cause the problem:

umount /huge

echo disk > /sys/power/state
# resumes fine

mount /huge
echo platform > /sys/power/disk
echo disk > /sys/power/state

FWIW, /huge is:

given the mount/umount thing this sounds unlikely... but what do I know?

resume does throw up:
ATA: abnormal status 0x7F on port 0x0001b007
ATA: abnormal status 0x7F on port 0x0001b007
ATA: abnormal status 0x7F on port 0x0001a407
ATA: abnormal status 0x7F on port 0x0001a407

which I've not noticed before... oh, alright, I'll check...
reboots to 2.6.21, suspend, resume...
nope, not output on resume in 2.6.21

Here is:
 dmesg from 2.6.22-9666f4009c22f6520ac3fb8a19c9e32ab973e828 (ie with sata_via 
fix)
