Good link - thanks. It did not fix my problem but as I was testing out all the options I discovered what the problem is likely to be
I noticed that I was always able to have a restart from the boot manager before
logging in but after a login restart would fail. Suspected a ram problem so ran memtest and got 96 fails in the first few minutes sooo thats gonna have to get fixed and then...
After chasing my tail for hours using memtest+
v1.70 that is with the Xfce 32 Maya ISO which reported thousands of errors on test 7
, I tried memtest+ v4.20
and came up clean - I like that one better
Back to testing the reboot fudges in grub, I found the most reliable to be GRUB_CMDLINE_LINUX=”reboot=force” (thanks to the link

Edit: None of the grub options work all of the time. REISUB does not reboot either.
