Howdy all,
	I'm attempting to use a Toshiba TECRA 8000 running 5.0-release as the
firewall for my home network.  It's running right now, but I'm seeing
some sketchy network behavior and I think it's one of the NICs. 
Basically, when I'm doing something fairly network-intensive (like large
NNTP downloads) my bandwidth usage fluctuates wildly.  I also will get a
lot of connections reset and such.
	I think it's my ed1 interface (which is my inside interface), because
when I had ed1 as my outside interface and in promiscuous mode (for
snort) I was getting a lot errors like:

Feb 14 15:00:37 elijah kernel: ed1: NIC memory corrupt - invalid packet
length 4
	When I changed my dc0 interface to be my outside, promiscuous
interface, these errors went away.  My current dmesg info is as follows.

ed1: <Linksys Combo EthernetCard> at port 0x100-0x11f irq 11 function 0
config 16 on pccard0
ed1: address 00:e0:98:88:91:84, type Linksys (16 bit)
ukphy0: <Generic IEEE 802.3u media interface> on miibus0
ukphy0:  10baseT, 10baseT-FDX, 100baseTX, 100baseTX-FDX, auto

dc0: <Xircom X3201 10/100BaseTX> port 0x1000-0x107f mem
0x88002400-0x880024ff,0x88002500-0x8800257f irq 11 at device 0.0 on
cardbus1
dc0: Ethernet address: 06:00:06:29:52:90
miibus1: <MII bus> on dc0
tdkphy0: <TDK 78Q2120 media interface> on miibus1
tdkphy0:  10baseT, 10baseT-FDX, 100baseTX, 100baseTX-FDX, auto

	Anyway, so I recently got a Xircom 10/100 cardbus NIC to replace my
linksys (ed1) card.  However, when I boot up with this NIC, I get to the
point where my interfaces are going to be configured (after setting
hostname) and the machine locks up.

	Here's the dmesg info for the new card.

dc1: <Xircom X3201 10/100BaseTX> port 0x1080-0x10ff mem
0x88002000-0x880020ff,0x88002100-0x8800217f irq 11 at device 0.0 on
cardbus0
dc1: Ethernet address: 06:00:10:a4:03:3f
miibus0: <MII bus> on dc1

Would it help if I rebuilt my kernel and specified the irq, mem and port
for dc0 and dc1?

Thanks in advance for any help,
