Suspend2 debugging info: - SUSPEND core : 2.2.9 - Kernel Version : 2.6.18-suspend2-r1 - Compiler vers. : 4.1 - Attempt number : 4 - Parameters : 17 16 0 1 0 0 - Overall expected compression percentage: 0. - Compressor is 'lzf'. - SwapAllocator active. Swap available for image: 250963 pages. - No I/O speed stats available. - Extra pages : -61 used/500. Reproducible: Sometimes Steps to Reproduce: 1. Try to hibernate to disk several times Actual Results: System will go to hibernating mode and will stop that process in the middle and failed to do so. Computer will continue to work after that. Expected Results: Hibernation should be successful. I was chatting on IRC with author and he said it's known problem and it has been fixed in 2.2.9.3. To fix it in the current stable 2.2.9 version you need to add the follow line to /etc/hibernate/suspend2.conf: ProcSetting full_pageset2 1
Unsupported kernel [1]; move this to http://bugzilla.suspend2.net/index.cgi [1] http://www.gentoo.org/doc/en/gentoo-kernel.xml#doc_chap3
I'm reopening the bug to confirm: The bug is known and it has been fixed in the next version as I mentioned early. So there is no point to file it in suspend2-bugzilla. However, it's possible to fix it in the current version by changing sys-power/hibernate-script package and adding the follow line to /etc/hibernate/suspend2.conf: ProcSetting full_pageset2 1 I would suggest to include that even commented out with explanations. Let me know if you need a proper patch.
I cannot document any workaround there is... You have found one... There are many with ati-drivers, drm, bluetooth, wireless etc... Suspend to disk is not supported very well in kernel... The workarounds can be found at upstream mailing list archives. Sorry.
Oh... And don't upgrade to 2.2.9.3, it has some major opened issues... :)
>Oh... And don't upgrade to 2.2.9.3, it has some major opened issues... :) That's exactly my point. The latest version is buggy and you can't use it. The 'stable' version is buggy too, but you need just a single line to make it work. At least for me. Anyway, I understand now why it's no supported :) I guess, I'll just document it on gentoo-wiki so people would know .. Thank you.
