This problem occurred while Kudzu was configuring a network card (Linksys LNE100TX). In the screen where it asks for IP information, I checked the box to use DHCP. Kudzu then briefly flashed a box saying it was running DHCP, but then returned to the same IP dialog. When I selected "Back", Kudzu bailed out (crashed?) and the boot sequence continued. I later found out that the card is unsupported, which explains why DHCP didn't work, but Kudzu should have given a message saying the card is not supported, rather than just getting stuck in a loop.
Actually, that card should be supported by the tulip driver. What did kudzu put in /etc/conf.modules, and what happens if you try to load the driver?
closed, lack of input.
