I was getting the following panic on 7.2-RELEASE-p4 a few times a day. I
removed all "route-to" from the ruleset and it's been 24 hours without any
panics.
Fatal trap 12: page fault while in kernel mode
cpuid = 0; apic id = 00
fault virtual address = 0xc
fault code = supervisor read, page not present
instruction pointer = 0x20:0xc0834736
stack pointer = 0x28:0xc3f5f974
frame pointer = 0x28:0xc3f5f9a0
code segment = base 0x0, limit 0xfffff, type 0x1b
= DPL 0, pres 1, def32 1, gran 1
processor eflags = interrupt enabled, resume, IOPL = 0
current process = 31 (irq23: rl0 ehci0)
trap number = 12
panic: page fault
cpuid = 0
