@532910 The first trace was from OpenWRT, right? Can you specify which version?
@PLangowski IIRC, you have tested booting with OpenWRT, can you provide more details?
OpenWRT is the latest stable of course: 23.05.3, exactly this image: https://downloads.openwrt.org/releases/23.05.3/targets/x86/64/openwrt-23.05.3-x86-64-generic-squashfs-combined-efi.img.gz
Moreover, while debian boots and looks like works fine, openwrt doesn't boot at all. Sounds like another issue, I'll provide more details a bit later.
First strace hit an undefined instruction right after a jump, so I have no idea why it happened:
0: c7 c6 60 4c 52 81 mov esi,0x81524c60
6: 8b b8 b4 03 00 00 mov edi,DWORD PTR [rax+0x3b4]

3c: eb 97 jmp 0xffffffffffffffd5
3e: 8b .byte 0x8b
3f: 7d .byte 0x7d
The other traces at least say that it is something related to IOMMU.
