swap gone after hibernate

I couldn't leave situation like this, reformated swap partition and tried hibernate with "nv" driver and I get exactly the same behaviour!
First hibernate does not resume, swap is here; second hibernate does not resume and swap is gone!

So I have ruled out nvidia driver being the reason here; the swap size is 1.16GB (should be enough for 512RAM).
I'm going to reformat swap again to re-enable it.

what a weird solution I have found!
it seems that if I add
resume=/dev/sda3
to
/boot/grub/menu.lst after the line "# defoptions="
then suspend to disk works perfectly!

I would still like to hear the reasons why I need "resume=/dev/sda3" to get successful hibernate

Guessing a more appropriate package.

Thank you for your bug report.

klerfayt:
When you reformatted the swap its UUID would have changed. I'm guessing that
cat /etc/initramfs-tools/conf.d/resume
is referencing a partition UUID that no longer exists (you can use vol_id /dev/sda3 to find the UUID for sda3). Can you include the output of
cat /etc/initramfs-tools/conf.d/resume
cat /etc/fstab
and
vol_id /dev/sda3
here please?

I have reinstalled kubuntu feisty fawn and repartitioned harddrive, however I can attempt suspend to disk (hibernate) without "resume=/dev/sda3" boot option if you want to again.
ps. this time I choose to make only 384MB swap partition (during installation it asks at least 256MB; is there an unwritten rule about swap size to ram size ratio? )

klerfayt:
There are quite a few suggestions as to the size of swap (some are out of date because memory can be in the 4Gbyte range). However because swap is used when you hibernate it's a good idea for it to be at least 1.5 times the size of real memory otherwise you may find yourself unable to hibernate due to lack of room to store the contents of RAM.

The missing /dev/sda3 is interesting (don't try and hibernate until that's resolved). Can you include the output of
uname -a
and
lscpi
?

I did complete reinstall to increase the size of swap to 768MB, however installation didn't let me choose exactly 768MB for swap, closest I could get was 773MB; what's even more strange is the fact I see 737.35MB swap size in kinfocenter now - where did the rest 36MB go?
also I redid cat /etc/initramfs-tools/conf.d/resume cat /etc/fstab and vol_id /dev/sda3 (haven't done hibernate or suspend to ram this time, and won't do now unless you ask)

klerfayt:
Hmm you're another sufferer of Bug #116996 so after the kernel upgrade to 2.6.20-16 your partitions will appear as /dev/hda1 etc. As all your partitions are referenced by UUID though this meant they could still be found despite this though! Can you again try a hibernate again with the nv driver?

do I understand you correctly that I have to attempt hibernate (suspend to disk) without boot option "resume=/dev/..."?
at the moment my boot options are default, the way installer set them:
root=UUID=bd4f623f-d761-4127-b0a2-07cb3d611691 ro quiet splash locale=et_EE

is bug #116996 related to failure of hibernation? or is it just another bug I have?

gutsy gibbon - nothing has changed, swap gone after first attempt to hibernate (suspend to disk); I believe hibernate was successful and resume from hibernate failed.

dmesg of boot with failed resume from hibernate

this is a fix for anyone experiencing the same problem:

sudo fdisk -l #see where your swap is, in my case /dev/sda1
sudo swapoff -a #turning swap off to reformat it
sudo apt-get install qtparted #use qtparted to reformat swap
sudo blkid #checking the new UUID of swap
kdesudo kate /etc/fstab #changing new UUID because we reformated
sudo swapon -a #turning swap back on
kdesudo kate /boot/grub/menu.lst #now we add "resume=/dev/path/to/your/swap" after the line beginning with"# defoptions="
#^an example: # defoptions=locale=et_EE resume=/dev/sda1
sudo update-grub
and done, reboot and test hibernate (works for me)

Is this symptom still reproducible in 8.10 beta?

No, it is not reproducible in 8.10 beta.
