I'm seeing similar issues: can't resume from hiberation after an update in late September, 2013.
dpkg-query -s uswsusp Package: uswsusp Status: install ok installed Priority: optional Section: admin Installed-Size: 575 Maintainer: Rodolfo García Peñas (kix) <k...@debian.org> Architecture: amd64 Version: 1.0+20120915-4 I note that changes to /etc/initramfs/... don't appear to do anything. The files in /usr/share/initramfs *do* appear to change things. E.g., setting RESUME in /etc branch doesn't do anything, based on echo from the /usr/share entry: $ cat /etc/initramfs-tools/conf.d/resume RESUME=/dev/blackbox/swap_1 $ sudo update-initramfs -u update-initramfs: Generating /boot/initrd.img-3.9-1-amd64 [...] DESTDIR: /var/tmp/mkinitramfs_6GLQDU RESUME: /dev/dm-1 Not sure if it's just using what's in /etc/uswsusp or not; looks like it: $ cat /etc/uswsusp.conf # /etc/uswsusp.conf(5) -- Configuration file for s2disk/s2both resume device = /dev/dm-1 compress = y early writeout = y image size = 1791197429 RSA key file = /etc/uswsusp.key shutdown method = platform what's printed during boot is /dev/dm-1, no matter what's in /etc/initramfs-tools... It hangs for about 5-10 minutes, then finally gives me an option to boot. However, no matter what I enter, it doesn't boot. That's at least consistent with the idea that LVM hasn't initialized properly yet, so no device can be found. However, / (root) is also in LVM, so..? $ mount | grep root /dev/mapper/blackbox-root on / type ext3 (rw,relatime,errors=remount-ro,barrier=1,data=ordered) $ cat /proc/swaps Filename Type Size Used Priority /dev/dm-1 partition 11149308 0 -1 i.e., $ ls -ltr /dev/blackbox/root lrwxrwxrwx 1 root root 7 Oct 23 18:42 /dev/blackbox/root -> ../dm-0 $ ls -ltr /dev/blackbox/swap_1 lrwxrwxrwx 1 root root 7 Oct 23 18:49 /dev/blackbox/swap_1 -> ../dm-1 $ sudo lvscan ACTIVE '/dev/blackbox/swap_1' [10.63 GiB] inherit ACTIVE '/dev/blackbox/boot' [100.00 MiB] inherit ACTIVE '/dev/blackbox/root' [1.86 GiB] inherit I'll try the "trick" of removing uswsusp and see if that .. changes things. Anything else I can provide to help?
