Probably, the important bit here is:
(XEN) d163v0 Unhandled page fault fault/trap [#14, ec=0003]
in conjunction with:
(XEN) RIP: e033:[<000000000041f42f>]
which I couldn't get to yield something using `addr2line`, but maybe I'm just
doing something wrong here.
Booting "regularly" with linux/ramdisk/extra arguments and grub-xen-host
2.04-20 works as expected.
Interestingly, grub-xen-bin 2.06-3 _inside_ the DomU doesn't cause any issues
(even in conjunction with 2.04-20 on the host's side); It's only when used as a
stub from the Dom0 side.
This behavior is reproducible on Debian 11.4, Kernel 5.10.0-17-amd64 and Xen
4.14.5+24-g87d90d511c-1 on an Intel Xeon E3-1225 v3 based box. My DomUs are
also running Debian with the same general package versions, however, this
doesn't seem to be relevant fot this bug as an "empty" guest leads to the same
result.
