Hi,

I have got an old 486-DX266 up and running with Netbsd 1.6.1. Everything
seems to be fine except that I am getting lockups on incoming telnets from a
Windows machine. I can telnet in fine from my Netbsd 1.4.1 system. The
network card installed is an ISA UM9008F, picked up as ne0 at base address
0x240, IRQ 10. I can ping and ftp into it fine from Win/BSD but the Windows
telnet freezes it up completely.

The tcpdump (before the freeze looks like this) ...

08:06:14.208269 arp who-has 192.168.34.220 tell 192.168.34.94
08:06:14.209445 arp reply 192.168.34.220 is-at 0:80:ad:1f:7a:81

Does anyone have any ideas how I could solve this?  Any help would be much
appreciated.
Regards
 Stuart
