Public bug reported: Hibernation with the pm-hibernate command works fine on a freshly booted system, but when a significant portion of the RAM is in use, for instance by starting gimp, google-chrome and firefox at the same time, it stalls at the start of the saving of the image data:
s2disk: Snapshotting system s2disk: System snapshot ready. Preparing to write s2disk: Image size: 441652 kilobytes s2disk: Free swap: 1798624 kilobytes s2disk: Saving 110413 image data pages (press backspace to abort) ... 0% The system is not usable at this point, although alt-sysrq still works. It looks like some sort of deadlock. The system is an Asus eeePC 1000HE with 2GB RAM and a 2GB swap partition and a Samsung SSD 840 EVO. The Ubuntu release is 14.04 LTS. The kernel package is linux-image-3.13.0-27-generic version 3.13.0-27.50 (32 bit). I found a kernel bug report that looks exactly the same: https://bugzilla.kernel.org/show_bug.cgi?id=75101 In that bug report, the problem was bisected to commit a1c3bfb2. This commit is part of the 3.14 kernel, but was apparently backported to the 3.13 Ubuntu kernel. I've rebuild the kernel package with this commit reverted, and it seems to fix this issue for me. ** Affects: linux (Ubuntu) Importance: Undecided Status: Incomplete ** Tags: trusty -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1328727 Title: s2disk/hibernate hangs during saving of image data To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1328727/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
