We have no specific Genode/seL4 x86 hardware list, but there exists an
unofficial list at [0] which may serve your question.

Thanks for testing.

May you please apply the seL4 kernel patch and test, whether this solves
your issue ?

Thank you^ that is very helpful

Here's my results from testing. I only used UEFI as it seemed not related to the issue: (but I will test legacy mode if you want, just let me know)

Permutation -- Result

UEFI: Multiboot2 w/ Bender -- failed assertion 'acpi_rsdt_mapped->header.length >= sizeof(acpi_header_t)

UEFI: Multiboot1 w/ Bender -- failed assertion 'acpi_rsdt_mapped->header.length >= sizeof(acpi_header_t)

UEFI: Multiboot2 -- freezes?

UEFI: Multiboot1 -- freezes?

Since I am new to Genode & seL4, I will elaborate just a little on the latter two cases. Video output is stuck on blank/plain "GRUB purple", serial output stops, and machine is overall unresponsive. Below is a paste of the serial output for UEFI Multiboot2 (which looks the same as Multiboot1)
