Hi guys,
I'm experiencing (somewhat random) panics every few days.
FreeBSD 10.0-STABLE #0 r265785
Fatal trap 12: page fault while in kernel mode
cpuid = 0; apic id = 00
fault virtual address = 0x378
fault code = supervisor read data, page not present

stack pointer = 0x28:0xfffffe034a534960
frame pointer = 0x28:0xfffffe034a5349f0
code segment = base 0x0, limit 0xfffff, type 0x1b
= DPL 0, pres 1, long 1, def32 0, gran 1
processor eflags = interrupt enabled, resume, IOPL = 0
current process = 0 (dummynet)
trap number = 12
panic: page fault
cpuid = 0

Full dump is available (actually four of them at this time) if
more info is needed.
Any ideas?
Kind regards.
