NetBSD  1.5L NetBSD 1.5L (GENERIC) #21: Tue Dec  5 13:54:21 UTC 2000     root@wyrm:/usr/obj/sys/arch/i386/compile/GENERIC i386

>Description:
	
This laptop (Toshiba Satellite T2130CT) has run netbsd since about 1.0
with this same 3Com pcmcia ethernet card.  Installation of 1.5 failed
when attempting to ifconfig ep0 to go fetch the install sets.
Various 1.5 kernels produced the same result, and 1.5L GENERIC kernel
also hangs.

>How-To-Repeat:
	

ifconfig ep0 inet 192.9.200.1 netmask 255.255.255.0 media 10baseT

we get:

and time to press reset or Ctrl-Alt-Esc.
