i386
I have rebuilt both the world and the kernel with sources from May 14th,
2001 to avoid possible inconsistencies.
My system has this network card:
ed0 at port 0x280-0x29f iomem 0xd8000-0xdbfff irq 3 on isa0
ed0: address 00:00:c0:e6:dc:6d, type SMC8216/SMC8216C (16 bit)
My network layout is very simple:
+------------------+ ed0 ed0 +------------------------+
| my box: 10.0.0.1 |---------------| client's box: 10.0.0.2 |
| 4.3-STABLE | | 4.2-RELEASE |
+------------------+ +------------------------+

>Description:
When doing a "netstat -nr" on my system to show the routing information
I get the following error:
sblank in ~ (3)> netstat -nr
Routing tables
Internet:
Destination Gateway Flags Refs Use Netif Expire
10 link#1 UC 0 0 ed0 =>
netstat: kvm_read: Bad address
10.0.0.2 0:0:c0:e7:40:65 UHLW 0 3 ed0 1197
127.0.0.1 127.0.0.1 UH 0 0 lo0
Notice the "Bad address" error displayed above. If I add the "-a" flag,
the error goes away.
