I have isolated the problem to be something with the hardware virtualization that is used by UNRAID to support VMs. I started by resetting my BIOS on my T610, created a fresh USB install and booted 6.10.0 RC3 and it booted successively. I then copied over all my configurations, plugins, etc. and booted again - again, it booted successfully. I went through to see if everything was working. I noticed that my VM's hadn't come online. At the top of the web-gui, it indicated that the hardware did not support KVM. I figured at this point that the resetting of the BIOS must have disabled the virtualization options. I went in the BIOS and enabled the virtualization technology on the processor and rebooted. The UNRAID boot splash came up and continued to boot normally until it hits the bzroot checksum failed. This is the ONLY change I made, so it must be related to the enablement of the virtualization technology in the BIOS. Now what???
