Hi,
I am seeing hibernation failures on a Framework Laptop 16 AMD Ryzen AI
300 Series. The best capture I have is from EFI pstore: the kernel
creates the hibernation image, then CPU0 soft-locks in the CPU stopper
thread and panics.
Impact: the machine powers/reboots instead of resuming the previous
session. The next boot reported no valid hibernation image.
System:
```text
Machine: Framework Laptop 16 (AMD Ryzen AI 300 Series)
DMI board: FRANMHCP09
BIOS: 03.06, 2026-04-23
Kernel: 7.1.2-arch3-1
Arch Linux
```
Kernel config has the debug options requested for this class of issue:
```text
CONFIG_HIBERNATION=y
CONFIG_PM_DEBUG=y
CONFIG_PM_SLEEP_DEBUG=y
CONFIG_SLUB_DEBUG=y
CONFIG_PAGE_POISONING=y
CONFIG_STACKTRACE=y
```
Relevant command line, with the root UUID elided:
```text
root=/dev/mapper/root rootfstype=btrfs rootflags=subvol=@ rw
resume=/dev/mapper/root resume_offset=4728064
rtc_cmos.use_acpi_alarm=1 drm.debug=0x1df log_buf_len=32M
ignore_loglevel printk.devkmsg=on slub_debug=UFPZ
```
The hibernate attempt was triggered by upowerd at low battery. A
systemd sleep hook ran before hibernation and captured:

There were no SLUB/page-poison corruption messages in the pstore
chunks, despite `slub_debug=UFPZ`.
An earlier hibernation pstore capture on the same kernel showed the
same broad failure class, also in `migration/0`, but with `RIP:
stop_machine_yield+0x6/0x10`.
I have attached:
```text
pstore-20260709-1748.tar.gz
hibernate-pre-20260709-174504.log
```
Please let me know what additional data would be useful. I can keep
the debug boot parameters enabled and retest with a proposed patch or
additional PM/debug options.

Follow-up: I reproduced this again with a cleaner case, so low battery
is not required.
This hibernate attempt was triggered manually with `systemctl
hibernate` at `2026-07-09T22:23:05+04:00`. The pre-hibernate hook
captured:
```text
BAT1 status=Discharging
BAT1 capacity=94
MemAvailable: 19404760 kB
SwapTotal: 48212748 kB
SwapFree: 48212748 kB
HardwareCorrupted: 0 kB
```
The machine failed to resume again. The next boot reported:
```text
systemd-hibernate-resume: Reported hibernation image: ID=arch
kernel=7.1.2-arch3-1 UUID=... offset=4728064
systemd-hibernate-resume: Unable to resume from device
'/dev/mapper/root' (253:0) offset 4728064, continuing boot process.
kernel: PM: Image not found (code -22)
```
Fresh pstore entries from `2026-07-09 22:24:14..22:24:18` show the
same failure class:
```text

```
No SLUB/page-poison corruption messages appeared in this pstore
capture either. AMDGPU appears in the PM freeze path, but both GPUs
returned successfully before image creation:
```text

I am attaching the new capture:

Thx for the report. You CCed the regression list, which leads to a
questions: what was the last version this was working?
Furthermore: Is mainline (7.2-rc) still affected?
And FWIW, if we are lucky some developer will show up in the next few
days with an idea what's wrong. But I doubt this will happen in this
case. So you most likely will have to bisect this to get this resolved:
https://docs.kernel.org/admin-guide/verify-bugs-and-bisect-regressions.html
https://docs.kernel.org/admin-guide/bug-bisect.html
Ciao, Thorsten
P.S.: Wild guess, but I wonder if this is related to (also waiting for
somebody to bisect):
