I looked around but I can't seem to find how to add the kernel. could 
you tell me the command(s) or docs to try it out. thanks

[denisj...@gmail.com]

I seem to have the same error booting. Using anything above Linux verston 
5.13.0-35-genertc
Ubuntu get stuck with the error below. Reading what has been said, my driver 
for ToughArmor MB992SKR-B would be the cause of the error and my inability to 
use the latest kernel.
