Details

Description: From kernel linux-6.2.3.arch1-1 onwards, my PC hangs during boot after "Loading initial ramdisk ...". Adding iommu=off or amd_iommu=off to the grub command line allows the PC to boot.

My PC uses a Ryzen 3 1300X CPU running on a Gigabyte AB350M-D3V MB
The GPU is a Gigabyte NVIDIA GeForce GT 1030

I'm using Grub as the boot loader

It appears @loqs has kindly offered to perform a git bisection in the forum thread. Please follow the instructions given there (i.e. install and test the kernels provided and reply with "good" or "bad"). We await the outcome.

Unfortunately the first kernel - linux-6.2.2.r499.g065a789b413a-1-x86_64.pkg.tar.zst - hangs

Do all the kernels need to be tested? loqs implies otherwise ("Assuming the last kernel was good").

With the last few bisections still to be confirmed I think it is the same issue as https://lore.kernel.org/linux-acpi/20230331235328.4312-1-lyude%40redhat.com/

Forum thread updated.

inux 6.2.10.arch1-1 (from repos) - hangs

kernel parameter 'amd_iommu=off' allows boot

Solved - This is fixed in 6.2.11-arch1-1
