Hello,
after upgrading the seL4 kernel (x86) from 3.1.0 to 3.2.0 we get for the

We bisected the commits between 3.1.0 and 3.2.0 and [0] is the first bad

These structs and functions seems to be generated only for the kernel

them on the user level side.
Do I just miss a configuration option ?

I'm not sure, whether here the Multiboot 2 information is incorrect or
the parsing by the kernel is too strict. Here one would require some
more investigation in the Multiboot 2 spec (overlapping regions are
valid or not?) and on the target machine in grub2
(Or at best use both
drivers and add a input multiplexer, e.g. [0], which takes both drivers
as input sources).
Beforehand you may just try the usb_hid [1] scenario to actual test
whether usb in general work on your machine(s).
[0] repos/os/src/server/input_merger/README
[1] repos/dde_linux/run/usb_
oot/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
ultiboot 2 Memory region overlap
Thanks for testing.
May you please apply the seL4 kernel patch and test, whether this solves
your issue ?

I would guess that now something is wrong with the ACPI
tables (content provided by the BIOS/UEFI of your machine or the parsing
in the kernel).

Camkes is another option.

't see an obvious way to keep the

changing the original code. Since the type of switch style and the ifdef

But let's see how you change it ;-)

Try to adhere to the
