look , fstab reads like this

# swap was on /dev/sda1 during installation
UUID=89534f2e-ad31-4941-87b0-22e9875efac8 none swap sw 0 0

and the /etc/initramfs-tools/conf.d/resume reads like this

vinny@vinny-HP-G62:~$ cat /etc/initramfs-tools/conf.d/resume
RESUME=UUID=89534f2e-ad31-4941-87b0-22e9875efac8

BUT blkid reads as thus

/dev/sda1: UUID="419b2146-8e8a-4d97-90ed-89e519e1dc0d" TYPE="swap"

Vinny, that's odd. Both fstab and resume show one (identical) UUID, but the output of blkid shows something different. I'm not sure what to make of this.

What's the output of

ls -l /dev/disk/by-uuid

ls -l /dev/disk/by-partuuid

ls -l /dev/disk/by-uuid

ls -l /dev/disk/by-partuuid

well what I make of it is when this install was "installed" the UUID of swap was what fstab and resume show,,,,,,,,but now it is different , and the only thing that was done that could possibly have changed it was to install Slackware to /dev/sda6 , I am sure I just pointed it at the existing swap partition but can not remember if it asked to format it or not ,,,,,,would a format of it change the UUID?
hear is the output of the 2 ls's

and

vinny@vinny-HP-G62:~$ ls -l /dev/disk/by-partuuid
ls: cannot access /dev/disk/by-partuuid: No such file or directory

I have changed the fstab and the resume file to reflect the current UUID of swap,,,, but if I understand you correctly I still knead to run a

sudo update-initramfs -u

correct ?

Yes, change both fstab and resume so that the UUID of the swap partition matches what you see in the output of blkid, and then update your initrd image.

The fact that you have no /dev/disk/by-partuuid is rather curious. What's the output of

ls -lR /dev/disk

Could it simply be that vinny's swap UUID changed during a re-partition or re-creation and fstab never got updated? This would only lead to swap failing after a delay during boot. Hardly noticeable unless you're right on top of it. A simple swapon -s would verify this.

like I said , the only thing that may have done anything to it was the installation of slackware a month or 2-3 ago and I beleve I just told it to use it in it's setup program (all text based) it was defenetly NOT repartitioned (by me) but slackware may have recreated it (my theory) any way hear is the swapon -s

vinny@vinny-HP-G62:~$ swapon -s
Filename Type Size Used Priority
/dev/sda1 partition 4096536 0 -1

however I dont see what that is verifying , in one of the last posts I sead I changed fstab to the current UUID of swap and even before I did swap was being used/listed correctly , pleas extrapolate ?

It looks like it loaded OK to me. I would have thought with your fstab UUID wrong, it wouldn't find the swap partition. <Perplexed>

<Perplexed> me to ,,,,, do I spell that bad that I am totaly not understood ? I did say "I CHANGED THE FSTAB TO REFLECT THE CURRENT UUID OF THE SWAP PARTITION"
but is was loading up ok before I did that .
now @oshunluvr are you just scanning the posts or reading them ,,,,,,,,,,

[oshunluvr]

<sheepishly grinning> Uh, yeah I missed that...

...anyway, yeah if you edited fstab and rebooted it would have worked...duh <slaps forehead>

Duh, I forgot. /dev/disk/by-partuuid exists only for GPT disks. Yours are all MBR, it appears. *smacks-head*

Aaa yes , well that enplanes that then ,,,,, I thought it looked like a GPT thing what with the "part" part and having read @oshunluvr's excellent GPT write ups :cool:

Lot of fore-head smacking coming out of this thread...

LOL ,,,,, my own included as I should have thought to check the swaps UUID (as we use these now) after the Slackware installation ......come to think of it , I should boot the 12.04 install and check what fstab & resume has to say about it their as well ,,,,,,,,,Duh vinny Duuuuh
