Which kind = of guest are you running? The trace shows xen_start -> hammer_time_xen and this path should _never_ be used by a HVM guest, this is only used by PVH guests. Can you install addr2= line from ports (it's in binutils) and run the following inside of the VM: # /usr/local/bin/addr2line -e /usr/lib/debug/boot/kernel/kernel.debug 0xffffffff81109cbb Is also any change that you could get the full boot output from the VM by connecting to it's serial console (and setting up the console inside of the guest). See https://www.freebsd.org/doc/handbook/serialconsole-setup.html Thanks. --=20 You are receiving this mail because: You are the assignee for the bug.=
