12.04 crashes when resuming from encrypted lvm volume

[Anton Kanishchev]

Using the command

sudo s2disk

the splash screen appears with the percentage bar -hibernation completes and the system turns itself off. The resume part worked on the same machine ,just not encrypted.

when it is time to resume from hibernate it asks for password to encrypted lvm volume -if password entered correctly it displays:
"successfully mounted sda-crypt[ etc etc] , resuming from sda....] it then hangs. can only see hdd activity for a few seconds before it hangs.

Is this a fault with the s2disk package or shall i try sudo pm-hibernate and see whether that works???

Anton Kanishchev, thank you for reporting this and helping make Ubuntu better. Could you please capture the oops following https://wiki.ubuntu.com/KernelTeam/KernelTeamBugPolicies#Capturing_OOPs ?
As well, if you could also please test the latest upstream kernel available that would be great. It will allow additional upstream developers to examine the issue. Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Once you've tested the upstream kernel, please remove the 'needs-upstream-testing' tag. This can be done by clicking on the yellow pencil icon next to the tag located at the bottom of the bug description and deleting the 'needs-upstream-testing' text. As well, please comment on which kernel version specifically you tested.

If this bug is fixed in the mainline kernel, please add the following tag 'kernel-fixed-upstream'.

If the mainline kernel does not fix this bug, please add the tag: 'kernel-bug-exists-upstream'.

If you are unable to test the mainline kernel, for example it will not boot, please add the tag: 'kernel-unable-to-test-upstream', and comment as to why specifically you were unable to test it.

Please let us know your results. Thanks in advance.

Ok-i followed the link about capturing oops ( https://wiki.ubuntu.com/KernelTeam/KernelTeamBugPolicies#Capturing_OOPs ).
have installed the package that it asked for. i have googled on how to find the oops log (http://www.pls-mc.com/content/view/221/374/) but /proc/kmsg doesnt display anything (doesnt open) and the other method does not work.

Am I missing something???

Will test upstream kernel later on today and will post results back tomorrow.

Anton Kanishchev, one thing I want to bring to your attention is the following article https://wiki.ubuntu.com/DebuggingKernelSuspendHibernateResume#Failure_due_to_encrypted_swap . Is this the situation you are facing?

[Anton Kanishchev (ak12-deactivatedaccount)]

Thanks for pointing that out Christopher, I used lvm ( using alternative install of 12.04lts) to set up my entire installation to be encrypted with AES.I followed the instructions given here( http://stonesifer.org/2011/07/01/dual-boot-windows-7-encrypted-with-ubuntu-1104-encrypted/ ) I guess that means that the swap is encrypted as well. Or does this issue occur only if you encrypt the home folder via the normal install? i suppose this bug is invalid now (previously reported issue). what should i mark it as(invalid?)?

Thanks very much for your help
