after reading this thread and https://bugs.launchpad.net/ubuntu/+source/linux/+bug/499940 and https://bugs.launchpad.net/initramfs-tools/+bug/538534
"PM Resume from disk failed " is the only error I saw in syslog, so I look in /etc/initramfs-tools/conf.d/ and surprised to find that it's an empty directory. Well I make /etc/initramfs-tools/conf.d/resume with RESUME=/dev/sda4 and then do sudo update-initramfs -u ( /dev/sda4 is my swap partition) then hibernate works - Thanks to whoever pointed it out :D Cheers! -- lucid regression: does not resume from hibernation https://bugs.launchpad.net/bugs/577916 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
