If you are interested in additional diagnostics, this is a very interesting part of the
Linux kernel testing ...
There was apparent hang in selftest/net/fcnal-test.sh as well.
I can help you with the diagnostics if you wish? Thanks.
If I could make them all work both on Ubuntu 22.10 kinetic kudu and AlmaLinux 8.7
stone smilodon (CentOS fork), this would be a milestone for me :)
Have a nice day!
Regards,
Mirsad
