Hi,
I have an elabnet professional bus master (PBM) on Debian server (armhf,
cubox-i). After upgrading from Debian 10 to Debian 11 owserver does not work
anymore. If I boot the Debian 11 system with the older kernel 4.19.0 from
Debian 10, owserver works again.
Is there any kernel dependency which I need to take care of when switching
from Kernel 4.19 to 5.10?
Here are some logs:

Are three any additional useful logs?
