>Description:
      Before i got a box for gateway machine I prepared in under VMware - it worked fine. Then I got a machine: COMPAQ Proliant 1600 with 2x p2 at 450, 256 ecc, smart 2dh with 2x 9,1 in mirroring and nics: on-board thunder and realtek 8139d. I put system from VMware to the box using ghost 8. Everything is working fine till natd is not started. When I start natd and first packets are switched system crashes with fatal trap 19: non-maskable interrupt while in kernel mode. First I tought that one of nic card is broken, so I've changed both from tl0+rl0 to ex0+rl0/another, rl0+rl1 - nothing. Then I ordered another Proliant box - nothing. Then machine crashes on console there are debug info: the common part is: current process: natd or irqxx:rl0. there is no such a problem if I'm using this two cards separately.
>How-To-Repeat:
      just run a box, natd and switch some packets
>Fix:
      don't run natd
