for me, pressing the reset button was enough, but I've experienced the
same problem with a dc0 and an ep1 on an otherwise identical machine (I
just swapped the nics).

I can reproduce the problem very consistently, BUT it worked very
nicely when I booted from floppy (during installation) and answered
"dhcp" to the network config question. Only when booting the actual
install kernel, it hangs everytime, and very hard.

Me too.


NB: I'm running on a self-made release using a clean CVS checkout
from the OPENBSD_3_5 tag, and touching nothing except disabling
building and installing X11 in the process (but using unchanged kernel
configs).
