Hi Nikolaus,
I got again some progress with my system but i got the following issues:

based on the branch letux-pvrsrvkm-v5.6.0-rc2
<https://github.com/openpvrsgx-devgroup/linux_openpvrsgx/tree/letux-pvrsrvkm-v5.6.0-rc2>
/ letux-pvrsrvkm
<https://github.com/openpvrsgx-devgroup/linux_openpvrsgx/tree/letux-pvrsrvkm-v5.6.0-rc2>
I get the following error when starting the userspace application:

When I'm using my rebased branch get the following:

root at busterarmhf:~# pvrsrvctl --no-module --start
[  653.025813] PVR_K:(Error): BridgedDispatchKM: Initialisation failed.

PVR:(Error): SrvInit: PVRSRVInitSrvConnect failed (4) [0, ]
pvrsrvctl: SrvInit failed (already initialized?)
(err=PVRSRV_ERROR_INIT_FAILURE)

Do you have any idea whats wrong or what I am missing in the rc2 branch?

I think I messed someting up in my rebase branch. So I will wait until you
rebased it next week.
