Description Eric Lan 2013-11-28 07:32:49 UTC

I am using linux mint debian edition (LMDE). If I hibernate the system shortly after logging in, it might succeed. After some operations, it takes two times of attempts of s2disk to hibernate successfully.

$ dmesg
[142528.245031] PM: Creating hibernation image:
[142528.248008] PM: Need to copy 530249 pages
[142528.248008] PM: Normal pages needed: 530249 + 1024, available pages: 518040
[142528.248008] PM: Not enough free memory

Supposedly, the free space in the swap may not be adequate. I then swapped off and then on to clean up the swap space to make all swap space available, which is confirmed by "free -h" command.

Then, s2disk still needs 2 attempts to hibernate successfully.

Could you try the latest upstream kernel v3.13-rc1?

Comment 2 Eric Lan 2013-11-29 03:06:29 UTC

Is there easier way to help you debug this ? The linux environment is a production system for me and I don't want to risk damaging it by upgrading to a release-candidate kernel.

Comment 3 Lan Tianyu 2013-11-29 03:27:24 UTC

You can't upgrade kernel? So how can you test a fix patch?

So far, I know a fix about hibernation swap allocation fix in the v3.13. This may fix the issue.

Comment 4 Eric Lan 2013-11-29 08:15:46 UTC

Because I had only 4G RAM and I used 64-bit LMDE, that might not fix it.

I am not familiar with the procedure. I found the most forefront Debian sid used the kernel 3.11-2, still lesser than v3.13. So it would involve re-compile and re-configure the kernel by myself right ?

Yes, you can follow this link to rebuild kernel.

It doesn't have anything to do with swap, it may be that we didn't preallocate/free enough memory during the start of hibernation. Please attach full dmesg after a failed hibernation.
