[Dell Inc. MXC061] hibernate/resume failure

That's odd, your dmesg doesn't show any attempt to resume. Mine looks like this:

[ 3.002362] PM: Starting manual resume from disk
[ 3.002365] PM: Resume from partition 8:5
[ 3.002367] PM: Checking hibernation image.
[ 3.002560] PM: Resume from disk failed.

(that's normal when the system wasn't hibernated)

Are you using any kind of custom kernel or initramfs on this system?

I'm using stock kernel and I don't know about initramfs, so I guess I'm using the default there also.

I do remember though that whenever I installed a kernel package under hardy I had a message like this:

update-initramfs: Generating /boot/initrd.img-2.6.24-22-generic
cryptsetup: WARNING: found more than one resume device candidate:
                     /dev/sda6
                     UUID=61e8a88a-3afc-4898-a4b8-b1434c534ab5

But cryptsetup isn't installed anymore under Jaunty and this warning doesn't appear in the last initramfs run:

update-initramfs: Generating /boot/initrd.img-2.6.28-11-generic

Are you using an encrypted root filesystem and/or swap?

Not that I know of :-)

Please attach:

/etc/initramfs-tools/conf.d/resume
/etc/fstab
/proc/swaps

 - mdz

Here they are

Thanks. So your fstab says your swap device is /dev/sda6, but the resume
process will be looking for a swap device by UUID
(61e8a88a-3afc-4898-a4b8-b1434c534ab5).

So we need to know if the UUID on /dev/sda6 matches. If it doesn't, then
that's the problem.

Please send the output of:

sudo vol_id /dev/sda6

ID_FS_USAGE=other
ID_FS_TYPE=swap
ID_FS_VERSION=2
ID_FS_UUID=ba984514-6bb2-43db-a4df-6fda91ed1621
ID_FS_UUID_ENC=ba984514-6bb2-43db-a4df-6fda91ed1621
ID_FS_LABEL=swap
ID_FS_LABEL_ENC=swap

So I guess, I need to fix something? Add UUID=ba984514-6bb2-43db-a4df-6fda91ed1621 to the fstab line and update /etc/initramfs-tools/conf.d/resume to that same value?

Correct. Replace /dev/sda6 with UUID=... in fstab and update
/etc/initramfs-tools/conf.d/resume with the same value.

I've updated the three files and attempted hibernate again with the exact same results. Again, there is no sign of an attempt to look for the resume device on boot after wards. I'm attachin the kern.log file, at the end you'll find the boot-up after the hibernation attempt, and the entry before that are what was printed when hibernation was requested.

Sorry, I should have mentioned...you'll need to run:

sudo update-initramfs -u

to rebuild the initramfs after updating the conf.d/resume file.
