I recently upgraded my kernel from 3.16.4 (Debian jessie) to 4.9.0 (Debian stretch). Everything was fine, until I tried to "Hibernate" (suspend to disk).
When I use Hibernate option in LXDE, it appears to hibernate. I can hear the disk spindle ticking and writing data. But the problems appears when resuming from hibernation. The kernel successfully restores the image from swap, but then freezes and reboots, with all that work lost. I could not find answer anywhere on internet. The people are just solving some mistakes around not setting /etc/initramfs-tools/conf.d/resume or have set kernel paramters, or have wrong entry in /etc/fstab. I have these correct. Correct UUID in /etc/initramfs-tools/conf.d/resume, correct fstab and not set resume kernel paramter.
I moved the swap partition outside of the extended partition to primary. The UUID was saved and applied to the new swap.
The system reaches "Restoring image 100%" and then "Suspending consoles", and then it powers off and boots normally, with all work lost.
Tried clean install, but without luck.
Happens only on i386 (32-bit x86), amd64 (64-bit x86) does not suffer.
Disk partition table layout:
NAME FSTYPE LABEL UUID MOUNTPOINT sda ├─sda1 ext4 HDD <ROOT-UUID> / └─sda2 swap HDD-SWAP <SW-UUID> [SWAP] sr0
The sda2 was logical(resides-inside-extended) before the upgrade.
UUID=<ROOT-UUID> / ext4 errors=remount-ro 0 1 UUID=<SW-UUID> none swap sw 0 0
BOOT_IMAGE=/boot/vmlinuz-4.9.0-3-686-pae root=UUID=<ROOT-UUID> ro quiet

(I know the processor is 64bit but it came with 32bit os originally, so I thought it was 32bit until I examined /proc/cpuinfo)
