--- Comment #6 from Claudio Eichenberger <t...@yourshop.com> --- (In reply to Graham Perrin from comment #1) During upgrade from 12.2 to 12.3, after the first 'freebsd-update install' the server still boots, but after the second 'freebsd-update install' no more. By the way, with 12.3 I can see that all boxes, not just this 'AMD EPYC 7371', signal the following problem during shutdown: cannot unmount '/var/log': device busy -- You are receiving this mail because: You are the assignee for the bug.
