I've found the issue and a workaround, although I think this is still a bug. The issue is that my swap was in a file on my main partition instead of in a separate swap partition. If having a swap file on a non- swap partition works for swap memory in all other respects, seems like it should also work for hibernating. Anyway, I got rid of the swap file and created a proper swap partition and hibernate was able to power down without immediately waking up.
I ran into another issue during the thaw (resume), which is unrelated to the bug, but I thought I would post my solution in case it helps someone. The issue was that it would just hang at a blank screen with a blinking cursor on resuming from hibernate. The solution was to create a /etc/initramfs-tools/conf.d/resume file with RESUME=/dev/sda5 in it, where /dev/sda5 is my swap partition. Then I was able to resume from future hibernations. -- hibernate fails (immediate thaw) https://bugs.launchpad.net/bugs/612399 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
