[KINDA SOLVED...] Reboot on Resume from Hibernate

naxan · 2011-07-24 18:14:57

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:

/etc/suspend.conf:

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

From /boot/grub/menu.lst:

# (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"

/etc/mkinitcpio.conf:

# 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.  For instance:
#     MODULES="piix ide_disk reiserfs"
MODULES="acpi-cpufreq cpufreq_ondemand i915"

# BINARIES
# This setting includes any additional binaries a given user may
# wish into the CPIO image.  This is run first, so it may be used to
# override the actual binaries used in a given hook.
# (Existing files are NOT overwritten if already added)
# BINARIES are dependency parsed, so you may safely ignore libraries
BINARIES=""

# FILES
# This setting is similar to BINARIES above, however, files are added
# as-is and are not parsed in any way.  This is useful for config files.
# Some users may wish to include modprobe.conf for custom module options
# like so:
#    FILES="/etc/modprobe.d/modprobe.conf"
FILES="/etc/modprobe.d/modprobe.conf /etc/suspend.conf /usr/share/kbd/consolefonts/ter-114n.psf.gz"

# HOOKS
# This is the most important setting in this file.  The HOOKS control the
# modules and scripts added to the image, and what happens at boot time.
# Order is important, and it is recommended that you do not change the
# order in which HOOKS are added.  Run 'mkinitcpio -H <hook name>' for
# help on a given hook.
# 'base' is _required_ unless you know precisely what you are doing.
# 'udev' is _required_ in order to automatically load modules
# 'filesystems' is _required_ unless you specify your fs modules in MODULES
# Examples:
##   This setup specifies all modules in the MODULES setting above.
##   No raid, lvm2, or encrypted root is needed.
#    HOOKS="base"
#
##   This setup will autodetect all modules for your system and should
##   work as a sane default
#    HOOKS="base udev autodetect pata scsi sata filesystems"
#
##   This is identical to the above, except the old ide subsystem is
##   used for IDE devices instead of the new pata subsystem.
#    HOOKS="base udev autodetect ide scsi sata filesystems"
#
##   This setup will generate a 'full' image which supports most systems.
##   No autodetection is done.
#    HOOKS="base udev pata scsi sata usb filesystems"
#
##   This setup assembles a pata mdadm array with an encrypted root FS.
##   Note: See 'mkinitcpio -H mdadm' for more information on raid devices.
#    HOOKS="base udev pata mdadm encrypt filesystems"
#
##   This setup loads an lvm2 volume group on a usb device.
#    HOOKS="base udev usb lvm2 filesystems"
HOOKS="base consolefont udev autodetect sata usbinput encrypt lvm2 uresume filesystems"

# COMPRESSION
# Use this to compress the initramfs image. With kernels earlier than
# 2.6.30, only gzip is supported, which is also the default. Newer kernels
# support gzip, bzip2 and lzma. Kernels 2.6.38 and later support xz
# compression.
#COMPRESSION="gzip"
#COMPRESSION="bzip2"
#COMPRESSION="lzma"
COMPRESSION="xz"
#COMPRESSION="lzop"

# COMPRESSION_OPTIONS
# Additional options for the compressor
#COMPRESSION_OPTIONS=""

Anyone having a similar problem, or have any suggestions what else I could try? I'm completely out of ideas!

Thanks.

[UPDATE]
The thread skunktrader points to seems to be the same issue, and downgrading to 2.6.38.5-1 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...

Wow, I don't know how I missed that post. Downgrading to kernel26 2.6.38.5-1 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 2.6.38.5 and 2.6.38.6 to break things...
