>Description:
Kernel randomly panics with following message:

Thus, I don't have crash dump file. I have apply patch in kern/59024 to have a crash dump for the next panic ;-)

Please note I'm not sure that first line is related to panic message.
>How-To-Repeat:
Panic randomly occurs. Thus, only boot 10.99.12 kernel and... wait.
