Thank you for the report Peter

Did it boot prior to 11.0-BETA2? ie; is it a regression?

Please report a bug in bugzilla with version: 11.0-BETA2 and cc
re at FreeBSD.org

If it's possible to obtain a backtrace of the panic, please include it
as an attachment:

Setting debug.debugger_on_panic=1 in loader may help get it to the debugger.
