>Description:
      From time to time kernel panic occurs. I can't see any dependency from somewhat - it can be once in a two days, but it can be a cople of times at row.
Box is Intel Celeron 2.4GHz on Intel board, 512Mb DDR (with highed timings, to exclude possible memory problems).
NIC's (onboard is turned off):
xl0 at pci1:0:0:   class=0x020000 card=0x00000000 chip=0x900110b7 rev=0x00 hdr=0x00
    vendor   = '3COM Corp, Networking Division'
    device   = '3C900-COMBO Fast Etherlink XL PCI Combo NIC'
fxp0 at pci1:1:0:  class=0x020000 card=0x10308086 chip=0x10308086 rev=0x08 hdr=0x00
    vendor   = 'Intel Corporation'
    device   = '82559 PCI Networking device'
fxp1 at pci1:2:0:  class=0x020000 card=0x000b8086 chip=0x12298086 rev=0x09 hdr=0x00
    vendor   = 'Intel Corporation'
    device   = '82550/1/7/8/9 EtherExpress PRO/100(B) Ethernet Adapter'

Trace of panic follows:
Fatal trap 12: page fault while in kernel mode
fault virtual address   = 0x53700689
fault code              = supervisor read, page not present
instruction pointer     = 0x8:0xc07525db
stack pointer           = 0x10:0xe06db220
frame pointer           = 0x10:0xe06db288
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         = 29 (swi1: net)
trap number             = 12
panic: page fault

>How-To-Repeat:
      Setup MPD (3.18.2) and FreeRADIUS from ports, bring these things to work, connect 20+ win-clients via VPN conection and say to them that INet is free today (to cause their activity :) ).
