During a recent upgrade (I forget the exact date when this started happening, but I've been trying to fix it on my own for a few months now) I began to have problems hibernating my laptop (a System76 Starling s4 netbook). I use LVM on top of a partition encrypted with DM-Crypt (thus my swap partition is encrypted after shutdown), which is an unusual configuration but up until now hasn't given me any problems.
When hibernating, everything SEEMS to work - the laptop shutdowns properly, and no obvious errors show up in /var/log/everything.log or /var/log/pm-suspend.log. After rebooting, everything looks good until the kernel finishes loading the hibernated image into RAM, at which point the system spontaneously reboots itself, and then loads as if there is no hibernate image to resume from. No messages are recorded in any logs until after the spontaneous reboot, however.
The only thing I've found is an indication that some systems may need to append the acpi_sleep=nonvs option to their kernel line in order to resume properly due to recent changes in how hibernation is handled. I've also tried switching between the kernel's built-in hibernation code, and the uswsusp backend. None of these has changed the resume behavior in the least (though uswsusp is a lot faster!).
Here's some relevant code:
snapshot device = /dev/snapshot resume device = /dev/mapper/critter-swap image size = 0 #suspend loglevel = 2 #compute checksum = y compress = y #encrypt = y early writeout = y splash = n shutdown method = platform threads = y
# (0) Arch Linux title Arch Linux root (hd0,0) kernel /vmlinuz26 root=/dev/mapper/critter-root cryptdevice=/dev/sda:crypto resume=/dev/mapper/critter-swap acpi_sleep=nonvs ro initrd /kernel26.img
/etc/pm/config.d/overrides (just the default tweaked for uswsusp):
# Default method to power down the system when hibernating. # If commented out, the system will use the kernel default as a # default value. # # Check /sys/power/disk for valid values. The default value # will be surrounded by [square brackets]. # HIBERNATE_MODE="shutdown" # Whether we need to post the video card when resuming from # hibernate. You should not normally need to set this. # In the future pm-utils will get this setting from HAL. # # Valid values are "no" and "yes" # HIBERNATE_RESUME_POST_VIDEO="no" # The default sleep/wake system to use. Valid values are: # kernel The built-in kernel suspend/resume support. # Use this if nothing else is supported on your system. # uswsusp If your system has support for the userspace # suspend programs (s2ram/s2disk/s2both), then use this. # tuxonice If your system has support for tuxonice, use this. # # The system defaults to "kernel" if this is commented out. SLEEP_MODULE="uswsusp" # These variables will be handled specially when we load files in # /etc/pm/config.d. # Multiple declarations of these environment variables will result in # their contents being concatenated instead of being overwritten. # If you need to unload any modules to suspend/resume, add them here. # SUSPEND_MODULES="" # If you want to keep hooks from running, add their names here. # HOOK_BLACKLIST="" # If you want to unconditionally add parameters to the commandline, # add them here. # ADD_PARAMETERS="" # If you want to ignore commandline parameters, add them here. # DROP_PARAMETERS="" # If you need to synchronize the system clock across a suspend/resume or # hibernate/thaw cycle, set this variable. # NEED_CLOCK_SYNC="true"
# vim:set ft=sh # MODULES # The following modules are loaded before any boot hooks are # run. Advanced users may wish to specify all system modules # in this array.

Anyone having a similar problem, or have any suggestions what else I could try? I'm completely out of ideas!
The thread skunktrader points to seems to be the same issue, and downgrading to 220.127.116.11-1 works as a temporary fix. Since this is essentially a duplicate thread, it seems best to monitor https://bbs.archlinux.org/viewtopic.php?id=119202 instead for more permanent fixes...

Sounds similar to this
Wow, I don't know how I missed that post. Downgrading to kernel26 18.104.22.168-1 indeed fixes the problem.
That said, EVERY subsequent kernel26 I've tested (every release except for what's in [testing]) seems to break resume from hibernate.
Downgrading is a temporary solution, but I'd love to have a better sense of what might have changed between 22.214.171.124 and 126.96.36.199 to break things...
