Just to mention, core and source are available, easy for me to provide more info! The panic thing happens during rc(8)/init/boot, haven't checked if manually processing same commands doesn't lead to panic, like it was the case with https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=230510 if I remember correctly. Will check tomorrow. Thanks for looking into it, -harry -- You are receiving this mail because: You are the assignee for the bug.
