WARNING: / was not properly dismounted.
The system has two ethernet cards (ISA - 3C509 and PCI - 3C590).
Each card has it's own IP and connected to two physically different
networks (ep0-194.90.1.0 vx0-194.90.6.0).
Here is the routing table:

routed -q is running. The system acts as a small ftp/http server.
It does not work as a router.
>Description:
For already a long time my system panics every few hours. I'm not sure
when exactly it started. The panic is completely unpredictable, it can occur
after 1-2 hours, and it can appear after 30-40 hours and it's not related to
any specific network (or other) activity.
Here is the panic message (copied from the screen, sorry for any mistakes):
Fatal trap 12: page fault while in kernel mode
fault virtual address = 0x1e
fault code = supervisor read, page not present
instruction pointer = 0x8:0xf014487d

processor eflags = interrupt enabled, resum, IOPL = 0

(I compiled kernel with DDB so i will be able to "catch" the message).
>How-To-Repeat:
There is no reliable way to repeat this.
>Fix:
I wish i knew, i suspect that it has something to do with multiple card
configuration. I'll disable the second card and check if the problem still
there.
