Hibernate resume fails intermittently: BIOS/UEFI memory map (e820) changes across boots

Summary

Hibernate resume fails intermittently because the BIOS/UEFI e820 memory map changes across boots. The kernel detects an inconsistent memory map and aborts restore with:

• Hibernate inconsistent memory map detected!
• PM: hibernation: Image mismatch: architecture specific data
• PM: hibernation: Failed to load image, recovering.

When the memory map is stable, resume succeeds. This appears to be a firmware bug (ACPI data region moves between boots).

System

• Product: Laptop 16 (AMD Ryzen AI 300 Series)
• Product version: A9
• Board name: FRANMHCP09
• BIOS vendor: INSYDE Corp.
• BIOS version: 03.04
• BIOS release date: 2025-11-06
• Platform firmware revision: 3.4
• System firmware (fwupd): 0.0.3.4 (latest, no updates available)
• Kernel: 6.18.6
• Secure Boot: off

Reproduction

1. Hibernate the system.
2. Resume from hibernation.
3. Failure is intermittent: sometimes resumes successfully, sometimes aborts with memory map mismatch.

Expected

Resume restores the hibernation image reliably.

Actual

Resume occasionally fails; the kernel detects an inconsistent memory map and refuses to restore.

Evidence

Two boots from the same kernel/config show different e820 layouts in the low memory ACPI data region:

Successful boot:

BIOS-e820: [mem 0x0000000009f3c000-0x000000006cd61fff] usable
BIOS-e820: [mem 0x000000006cd62000-0x000000006cd6dfff] ACPI data
BIOS-e820: [mem 0x000000006cd6e000-0x000000007094dfff] usable

Failed boot:

BIOS-e820: [mem 0x0000000009f3c000-0x000000006cd68fff] usable
BIOS-e820: [mem 0x000000006cd69000-0x000000006cd74fff] ACPI data
BIOS-e820: [mem 0x000000006cd75000-0x000000007094dfff] usable

The ACPI data region shifts between boots, which changes the memory map and makes the hibernation image incompatible with the new boot.

Notes

• Same boot entry, same kernel, no BIOS/UEFI settings changed.
• test_resume works when the memory map remains stable within a boot.
• fwupd reports system firmware is already up to date.
