Tuxonice stopped working with kernel upgrade to 2.6.31

I have had Tuxonice working reliably on an amd64 system with 2.6.30 for a month, after it worked well on 2.6.29 for about four months. Though it refused to recognize that LZO compression existed with 2.6.30, it hibernated without using compression. So I upgraded the kernel to try to overcome this problem. Now it hangs when I try to hibernate.

Hardware: Dell Latitude D520 with Core 2 Duo CPU and Intel 945GM graphics.

From /var/log/hibernate.log:

I doubt that the compressor is your problem. What happens if you
comment out the compressor line in hibernate.conf?

sorry for th red herring - on my system without lzo I get the
"disabling" message but hibernation proceeds to work fine ...

The disabling message was what I got with 2.6.30. But with LZO commented out now in 2.6.31, I now seem to be getting perfectly working suspend and resume, and it does both about three times faster than with 2.6.30.

So thanks for the red herring.

But I'd still like to know why LZO is not working.

where are you suspending to?

The location (specified on the grub.conf kernel line) is /dev/sda7 which is a 1GB swap partition.

Interesting. Now it works with LZO compression. But on my trial run, with the compression takes about two seconds longer, both on the suspend and the restore. Is that normal?

I still have no idea why it would hang previously, giving the error message (copied from the log file)

Now it has stopped hibernating again.

From messages:

Works without compression. I'll crank up the log level and see if I get any ideas.

With LogVerbosity set to 4, and lzo compression re-enabled, it works normally (once, anyway). But I can see now that the uncompressed size is under 100 megabytes, less than 10% of my swap space, so I'm leaving it with no compression until it gives some trouble. It's faster, and seems more reliable.

Unfortunately I am having a similar issue. I am not exactly sure when it stopped working, my *guess* is after the udev update some days ago. My current kernel is 2.6.31.5 (vanilla-sources).

tuxonice.conf

Never mind, upgrading to 2.6.31.6 solved the problem.
