Tejun, all the problematic patches are yours - so adding you.

Ouch....
<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.

given the first patch identified is
9666f4009c22f6520ac3fb8a19c9e32ab973e828: "libata: reimplement suspend/resume
support using sdev->manage_start_stop"
That seems a good candidate...

9ce3075c20d458040138690edfdf6446664ec3ee works, right?
Yes
git reset --hard ec4883b015c3212f6f6d04fb2ff45f528492f598

 Can you test
9666f4009c22f6520ac3fb8a19c9e32ab973e828 by removing
ata_scsi_device_suspend/resume callbacks from sata_via.c?   Just delete
all lines referencing those two functions.  There were one or two
fallouts from the conversion.

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

mount /huge
echo platform > /sys/power/disk
echo disk > /sys/power/state
# won't resume

FWIW, /huge is:

How many drives do you have?
8 in total
2 pata : VIA vt8237
2 sata on sata_via
4 sata on sata_promise
+1 pata cdrom

  Behavior difference introduced by the
reimplementation is serialization of resume sequence, so it takes more
time.  My test machine had problems resuming if resume took too long
even with the previous implementation.  It didn't matter whether the
long resuming sequence is caused by too many controllers or explicit
ssleep().  If time needed for resume sequence is over certain threshold,
machine hangs while resuming.  I thought it was a BIOS glitch and didn't
dig into it but you might be seeing the same issue.
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


Please post dmesg too.  Thanks.


Here is:

fix)
