apologies for crossposting - feel free to direct me to the correct place
and/or ignore other versions...  i started a reddit-thread HERE
<https://www.reddit.com/r/openbsd/comments/17g1h5d/apu4_real_com0_boot_not_working_to_install_74/>
which
didnt specify which list specifically - but provided a very-useful
help/ftp-site to bisect when the problem occurred...

i have a pcengines apu4 which has been running 7.1-stable with all updates
just fine...  i had been avoiding doing an upgrade - so was thinking to
reinstall based on 7.4-release this week...  i was unable to do an install
from the bsd.rd (for 7.4) - and have bisected the issue to somewhere around
the 9th or 10th of september...

i will enclose the bug-report-info i just now collected from the
running-machine...  the symptom is: the bsd.rd seems to time-out/fail at
the very-beginning from com0 and then forces a reboot to the system...

onscreen - the com0 output for two) successful bsd.rd looks as follows:

tia, h.

ps - i accidentally mis-titled an earlier bug-report about this same
issue...  i was tired and thought i was dealing with my zotac-id89
device...  sorry, but in that mis-titled bug-report i had included a full
sendbug output from root-user...  i doubt whether that is relevant, but
please let me know what (if anything to do/try next)...  sincerely, h.
