Unfortunately, nothing related to kernel lockdowns. My kernel sysrq also
doesn't seem to recognize x, and neither dmesg nor system...

Can you please check system logs and output of dmesg?
I've managed to run into this article [1] that explains that even if you
have all permissions and no SELinux you can still be blocked by
something called kernel_lockdown and it should appear in dmesg.

USB-hotplugging fails with "failed to load cgroup BPF prog: Operation not permitted" on cgroups v2
Hi all,
I've disabled cgroups v1 on my system with the kernel boot option
"systemd.unified_cgroup_hierarchy=1". Since doing so, USB hotplugging
fails to work, seemingly due to a permissions problem with BPF. Please
note that the technique I'm going to describe worked just fine for
hotplugging USB devices to running domains until this change.
