This patch causes the loongarch virtual machine to fail to start the

Oh, another spot that needs special handling ... I see Alexander already
sent a patch (thanks!), but anyway, this is a good indication that we're
missing some test coverage in the CI.
Are there any loongarch kernel images available for public download
somewhere? If so, we really should add an avocado regression test for this
- since as far as I can see, we don't have any tests for loongarch in
tests/avocado yet?
we can get some binarys at:

I'm not sure that avacodo testing can be done using just the kernel.
Is a full loongarch system required?
No, you don't need a full distro installation, just a kernel with ramdisk
(which is also available there) is good enough for a basic test, e.g. just
check whether the kernel boots to a certain point is good enough to provide
a basic sanity test. If you then can also get even into a shell (of the
ramdisk), you can check some additional stuff in the sysfs or "dmesg"
output, see for example tests/avocado/machine_s390_ccw_virtio.py which does
such checks with a kernel and initrd on s390x.
