Hello. I feel I’m at the end of my limited ability to troubleshoot this and would greatly appreciate any help.
*Intermittent meaning when it hangs on boot I may have to soft reboot it once, or more than half a dozen times, before it reaches the login screen.
Here’s some output that may shed light:
$ cat /proc/cmdline
