SubjectBug#1124340: linux-image-5.10.0-37-amd64: Boot and shutdown screens filled with copyright characters
Message-ID<M7OPf-6RDF-3@gated-at.bofh.it>
Package: src:linux
Version: 5.10.247-1
Followup-For: Bug #1124288

Dear Maintainer,

After upgrading to linux-image-5.10.0-37-amd64, all the tty screens
except for tty1 are filled with copyright symbols.  Typing in these
screens will move the cursor, but not produce readable text.  tty1 is
unaffected, as well as gui (xorg).  Booting an older kernel will restore
proper behavior.

Note: the report below is done on a VM.  This was to confirm the bug
applies to debian.  It was initially noticed on devuan, on actual
hardware.  If it would help, I could send a reportbug from that system
also.

Thanks for your report. This is the same as #1123750, so I'm merging
both reports.
