If you were not having these panic attacks before the update, one of the things that worked for me was simplifying the boot arguments list for Clover to the bare minimum I needed to get the station booting. Once that was done I tried one by one enabling the boot arguments I knew I needed. For example the NVidia boot arguments. Just getting that to work can be difficult. If you find yourself struggling, maybe consider downgrading to 10.13.2 again if it was working for you before. There is no need to rush to 10.13.3 just yet. You have the option of waiting for others to iron out the issues before moving up to a new OS version. I moved too quick and loaded 10.13.3 and now internet browsers on my station are buggy, choppy and slow. And I do not know the reason yet. I'm trying the simplest updates to things that might have something to do with how the Nic card works on motherboard. I thought that maybe Apple's new file system might have something to do with the slow downs, so I tried updating apfs.efi. That didn't work so I moved on from there. I might try installing the RealTec drivers again. Or maybe there is a new one I could look for. The process is slow and methodical. A quick google search of the last message of your attached image yielded this:

However that error might also point to something being wrong with how Clover is setup as far as memory and memory handling is concerned. Just a thought. There are incredibly talented people on this forum who will have a much better idea of what is happening to your system than me.
