--- Comment #1 from Kubilay Kocak <koobs at FreeBSD.org> ---
Thank you for your report
Could you please include more information, including:
- Exact FreeBSD version (uname -a)
- /var/run/dmesg.boot output (as an attachment)
- Check and confirm that the file system is clean (fsck -fy in single user), or
report back if it is not
- See if you can obtain a kernel panic backtrace [1], and in particular try to
catch the initial "panic message"
- Clarify whether or not the panic is reproducible *without* MAC_BIBA and/or
multilabel enabled (test each combination)
