Arch Linux

Description:
ArchLinux does not resume properly after suspend from RAM due to an AMD IOMMU bug/oops about interrupts enabling.


Additional info:
* linux 5.17.1 mainline kernel
* Thinkpad T495 Ryzen 7 3700U with Radeon Vega RX10 (iGPU)
* I'm planning to report this upstream to the Linux kernel (Bugzilla) on the IOMMU driver.
* This issue started very recently on this kernel, I believe the oldest working one was 5.16.16 maybe the regression was introduced by the 5.17 kernel.

Steps to reproduce:
- Boot on linux 5.17.1
- systemctl suspend
- Push power button.
- The issue thus is triggered if any X11 graphic server was started the system cannot resume from suspend to RAM (black screen) and a force reboot is needed.

The output from dmesg given here was done using `no_console_suspend`, `initcall_debug` and `ignore_loglevel`.

Here is the relevant output :
