Dont CC maintainers when you cannot assign bugs.
Comment 2 Toralf Förster gentoo-dev 2008-12-03 08:54:25 UTC
Tested 2.6.28-rc7 where that issue seems to be gone.
Comment 3 Daniel Drake (RETIRED) gentoo-dev 2008-12-03 11:40:13 UTC
So, to clarify:

You boot the system
You suspend-to-ram
You wake it up

everything fine so far?

Then you attempt to suspend-to-disk, but the system does not suspend, and you end up with some messages in /var/log/messages ?

Does it work if you avoid the suspend-to-ram first?

Your /var/log/messages is lossy. Some important messages are missing from near the top. Please get the messages from dmesg instead, you may need to increase CONFIG_LOG_BUF_SHIFT for them all to be saved.
Comment 4 Markos Chandras (RETIRED) gentoo-dev 2008-12-03 11:51:27 UTC
Please provide dmesg output when you are trying to suspend-to-disk.

/var/log/message excerpt

I booted 2.6.27-gentoo-r4 with "init 2", therefore only acpid, syslog-ng and dnsmasq were started.
Then I suspended the system 3 times in a row w/o any problems each by pressing Fn+F4. Then I pressed Fn+F12 to hibernate the system, got the expected, but unwanted result, pulled a face and rebooted into working kernel 2.6.26-gentoo-r3.
Comment 6 Daniel Drake (RETIRED) gentoo-dev 2008-12-03 13:02:51 UTC
Toralf, please reply to comment #3. I'm not sure if I'm understanding the bug correctly, you're suspending-to-ram and then to disk? Does it make any difference if you don't suspend to ram first?
Comment 7 Toralf Förster gentoo-dev 2008-12-03 14:02:46 UTC
(In reply to comment #6)

with these terms :

Fn+F4  == "suspend"   == supend-to-ram
Fn+F12 == "hibernate" == suspend-to-disk

I booted some minutes ago into that kernel (init 2) and could hibernate 2 times in a row w/o problems. Then I suspended, waked up and hibernated the system. That worked as expected.
therefore it looks currently to me as a problem, if I first suspend a system after a (re-)boot and later try to hibernate it (which is unfortunately exactly my workflow when I travel from work to home and go back to my work location  next day, which is too long for the battery).

Comment 8 Markos Chandras (RETIRED) gentoo-dev 2008-12-03 17:44:55 UTC
Seems to be an upstream bug. Please report it on kernel bugzilla ( ). Please make sure to clarify on which kernel works and on which it doesnt.

Remember to post your newest /var/log/messages while submitting the bug

When you open the bug on kernel bugzilla, please post the link here. 

Many thanks
