Newly installed FreeBSD 12.1 and 11.4 immediately freezes when loading oce by running
kldload if_oce. The whole system becomes locked up at this time. CTRL+c and CTRL+z don't work.
What is the starting point to find out the problem cause?
Why does the process make the whole FreeBSD unresponsive and the only option is to reboot?
I already encountered such problem with
mount and zfs operations.
