Sure - I've tried a few different combinations, but the latest Genode

used seL4 9.0.1. I'm attempting to use this on an x86 machine that has a Xeon 1607 and a dedicated GPU. The thread I referenced in my initial post implied that UEFI might be an issue, but I've tried both UEFI and legacy boots without success. I tried using/building Genode 17.5 with whatever version of seL4 it acquires, but get the same error. Let me know if there's anything else I can provide

some suggestions from my side.

Try to remove the chain bootloader "bender", just to exclude it as potential reason of trouble. In genode/tool/run/boot_dir/sel4 remove the "multiboot2 /boot/bender ..." line and adjust the line below from "module2 /boot/sel4 ..." -> "multiboot2 /boot/sel4 ...". Use some simple scenario for testing, like log.run

If the issue persists, you may try to boot Genode/seL4 the Multiboot 1 way instead of Multiboot 2, which however will solely work for BIOS legacy boots (no UEFI). Replace the "multiboot2" and "module2" in genode/tool/run/boot_dir/sel4 with "multiboot" and "module".

Cheers,

Alex B.

Here's my results from these permutations, using Genode 18.05 / sel4 9.0.1 (hopefully the formatting works). I know some permutations probably don't make sense, but I did them anyways. Any thoughts? I have the serial output from these tests as well, but didn't want to overload this message with that. Additionally, can you folks share specific machine make/models that you know work with Genode/seL4? Hopefully some 'consumer off the shelf' stuff.
