Without specifying kern.vty, I get vt. With kern.vty="sc" in /boot/loader.conf, graphics failed after appearance of EFI framebuffer information <https://photos.app.goo.gl/bxQ44dqjvoBUDT2p6>, however disk activity continued <https://photos.app.goo.gl/VTvjpmKuyw2ksawu9>; and eventually, through use of the power button, I could repeatedly sleep then wake the computer (albeit without graphics). (Compare with vt, where things fail hard and quickly at wake time; no response to the power button.) Back to vt. I wondered whether screen.font in loader.conf might have an impact. No better after commenting out the line. For 470.57.02 there's a patch and commentary at/around <https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=257456#c4>. I might try this. Any other suggestions? TIA
