https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D244118 --- Comment #8 from Mark Millard <marklmi26-fbsd@yahoo.com> --- (In reply to Francis Little from comment #7) If you have an appropriate swap/paging partition you might be able to have /boot/loader.conf contain an assignment of the general form: dumpdev=3D"/dev/<???>" (substituting as necessary). Then you might be able to cause a kernel dump from ddb (say). (Of cource, this might run back into the same or other problems.) If it worked, rebooting with vm.debug.uma_multipage_slabs=3D"0" should pick up that dump if you have room in /var/crash. The dump might contain the tail of the sequence of lines that would have gone into the log file. There might be a way to extract those lines. --=20 You are receiving this mail because: You are the assignee for the bug.=
