PCEngines firmware version
Currently v4.19.0.1, but previous firmware releases were also affected.
APU variant
apu2e4
OS and OS Version
Linux apu2e 6.1.4-gentoo #3 SMP Sat Feb 4 14:42:43 GMT 2023 x86_64 AMD GX-412TC SOC AuthenticAMD GNU/Linux
Affected component(s), peripheral(s) or functionality
~20 second boot delay and kernel warning issued.
Brief summary
I have the AMD IOMMU enabled in the BIOS settings.
On every boot with at least every 5.x and 6.x kernel, the boot sequence output reads:

How reproducible
Every boot.
How to reproduce
Steps to reproduce the behavior:
- Enable IOMMU in BIOS settings
- Reboot apu2e4
- Observe kernel boot-log output
Expected behavior
Kernel WARNINGs shouldn't be triggered.
Actual behavior
There is a ~20s delay during the early-boot sequence and then the above WARNING is output.
(I believe that @metux is the kernel maintainer for APU boards? This may be unrelated if this is a general IOMMU issue...)

same on apu4c4, apu4d4

on my debian 5 system I switched from kvm to xen
(installed/apt get xen)...
no more errors regarding iommu in dmesg
i have no idea about the difference... or how it fixed it... but currently the only work around.
Since we don't know what this crash represents... (it seems to have no impact)
