>Description:
This is actually a multipart problem. When MAC is enabled, and running accton, the kernel panics. That's the first part. The second part is that the core dump to dumpdev fails. The third part is that with dumping disabled, even when PANIC_REBOOT_WAIT_TIME is enabled and set to 10, it does not automatically reboot. Filing this first, so as to unravel the onion.
Fatal trap 12: page fault while in kernel mode
cpuid = 1; apic id = 01
fault virtual address = 0x18
fault code = supervisor read data, page not present

Automatic reboot in 10 seconds - press a key on the console to abort
>How-To-Repeat:
Enable biba/mls/lomac/partition, set all to active, run accton. Kernel panics via kassert in mac_get_label.
