Hibernation can be a pig to get going. BillK -----Original Message----- From: Timur Aydin <ta@taydin.org> Reply-to: gentoo-user@lists.gentoo.org To: gentoo-user@lists.gentoo.org Subject: [gentoo-user] Weird hibernate problem Date: Mon, 10 Sep 2012 23:06:17 +0300 After corrupting my gentoo root filesystem system during hibernate experiments, I have finally finished the reinstallation. But hibernate still doesn't seem to work correctly. The symptoms are the same as during the experiments leading to the root fs corruption, but this time the root seems to remain intact. Here is what happened during the first experiment. I had an 8G swap partition as /dev/sda5 and a data partition as /dev/sda6. Thinking that pm-hibernate requires a dedicated, separate partition, I backed up /dev/sda6, turned off swap at /dev/sda5, deleted /dev/sda[56] and then created /dev/sda5 (8G), /dev/sda6 (8G) and /dev/sda7 (remaining size) Then I specified /dev/sda6 as the resume partition on the kernel command line. But when I did the pm-hibernate, the system powered off, and after reboot, the system seemed to have restored itself to the state it was at when I ran pm-hibernate. So it "seemed" to have worked, but the system was strangely unstable. There were many filesystem errors in the root partition and when I did a ps ax, I saw hundreds of kworker kernel threads lingering around. It was as if the hibernate image was slightly corrupted, but not enough to cause a complete lockup, but enough to cause there strange symptoms. I first thought this was related to using the swap partition as the resume destination. But after reinstalling gentoo, I again used a separate partition for hibernate, but I am still seeing the same symtoms. Many kworker kernel threads are sleeping. But this time, the root filesystem didn't have any error. Concerned that a filesystem corruption is imminent, I immediately turned off power. So, what could be causing these strange problems? Based on what I have read so far, the resume partition needs to be an active swap partition. This seems rather strange, because linux is using the swap partition for memory management as well. So shouldn't these be well separated to prevent corrupting each other? Hope someone can help me make sense of all of this...
