it worked the first time after restarting the system (serial cable *not*
connected) and therefore testing the newly written image. Then shutting
it down and turning it on again it reset in several boot attempts after
loading the GRUB payload(?) *with* the serial cable connected (PSU
turned off each time for one or two seconds) until it finally
successfully started again.

I think I had already seen this some weeks ago, but did not have time
yet to report this issue.
