Hi.
I get fatal trap 12 every time when mpd runned on my machine trying to
recieve a new pppoe connection and doing some netgraph manipulations.
Same configuration is working fine on 4.9-STABLE.
I got something like:
Fatal trap 12: page fault while in kernel mode
cpiid=0; apic id=00
fault virtual address = 0x1C
fault code = supervisor write; page not present
code segment = base 0x0, limit 0xfffff, type 0x1b
= DPL 0, pres 1, def32 1
current process = 38 (swi1:net)
After that system tryes to sync caches but hangs.
Here are my dmesg out:
