hello stormking I have the same problem, and it is for me clearly visible when doing make clean bzImage modules modules_install, of course when I modprobe 3c2000 too

and your post is the only thing I see on google about 3c2000 __udivdi3
I am working with gentoo-sources 2.4.22-r5 (if you don't know gentoo, that is one of the available kernel packages on gentoo, which is the standard kernel with some gentoo patches)
have you found a solution?
TIA
