Isn't there a simpler way too solve this issue ... ?!?
I was thinking about making screenshots of the firewall rules.
Clearing the firewall to factory settings.
Manually add all the rules.

Anyway, I don't know what you mean by having a look at my boot.log, dmesg log and my messages log while booting for errors.
I have no experience with log files and at the moment I refuse to reboot, because it can take a sometimes 20 times before it boots up again.
This problem has always been there, even after I changed HD's and did a full reinstall.

A reinstall is not an option, because it would not solve the boot issues and I would lose a lot of data that I cannot backup on another disk right now.
