Public bug reported:
After upgrading from linux-image-7.0.0-28-generic (7.0.0-28.28~24.04.1) to
linux-image-7.0.0-30-generic (7.0.0-30.30~24.04.1), hibernation no longer
completes on a Lenovo ThinkBook 16 G5+ ARP (Radeon 680M / Rembrandt, 1002:1681).
The hibernation image is created and written to swap successfully, but
immediately before power-off the kernel detects a wakeup event and rolls the
hibernation back. The rollback itself is not the fatal part: on the way back up
amdgpu fails to suspend/resume its PSP IP block, enters a GPU reset loop, and
the graphical session dies. The machine has to be rebooted forcibly.
On 7.0.0-28 the exact same setup hibernated successfully 19 times in a row over
about two weeks. On 7.0.0-30 it failed on both attempts (2 of 2).
--- Steps to reproduce ---
1. Boot 7.0.0-30-generic.
2. systemctl hibernate (or hibernate from the GNOME menu)
3. Observe: system does not power off; screen goes black/unresponsive, GPU
resets repeatedly, gnome-shell crashes.
--- Expected ---
System powers off and resumes from the hibernation image (as on
7.0.0-28).
--- Actual ---
Image is written, hibernation is rolled back, amdgpu wedges.

linux-image-generic-hwe-24.04 was upgraded 7.0.0-28.28~24.04.1 ->
7.0.0-30.30~24.04.1 on 2026-08-31 00:50 (per /var/log/dpkg.log). The first
failure followed on the first hibernation attempt on the new kernel.
Booting 7.0.0-28-generic is a working workaround.

--- Notes ---
The hibernation configuration is unchanged since it was set up in April 2026
(/etc/default/grub untouched since 2026-08-19), swap is large enough for the
image, and resume=/resume_offset= are correct - the image writes and the
"rolling back" happens after a complete, successful write.
I have not been able to identify what generates the wakeup event. It happens
in the second freeze phase, after the image write, on both attempts.
