Boot Loop in Mojave

I just upgraded to Success' href='/2020/12/install-macos-mojave-on-supported-pc.html'>Mojave from High Sierra. I had to weed out some old kexts to get sound to work. The system worked fine for a week until today. Now when I start the boot of OSX from Clover, the Apple progress bar proceeds half way across and the system re-boots. The only thing I did differently today was I left a USB drive inserted in one of the reports when I was booting the system. I don't think that should have changed any thing.

I can work around the boot problem by using the -x...
