Created attachment 31718 [details] .config used to compile the kernel I am a dummy. Here is the config I used to compile the kernel.
I'm having a very similar problem when trying linux-2.6.6-uml1.

I have 2 machines running Gentoo, one a P4 3GHz and one an Athlon XP3200+. I successfully compiled on the P4 machine, but on the Athlon I received the same errors reported in the current bug report. Both machines have very similar configuration since I used the same make.conf (except for architecture selection) and I used NPTL on the Athlon. My "emerge info" is posted below. Googling on the "multiple definition of xxx" error produced two results: 1. A patch correcting this error was submitted to the 2.6 kernel a long time ago and is being used in the Gentoo ebuild. 2. UML does not currently support NPTL. Check your configs (I note a couple nptl USE flags). Moving back down to linuxthreads corrected this problem for me.

This bug appears to be a duplicate of 49277; I don't have rights to mark it as a duplicate though. If Christopher Eineke (the reporter) agrees, perhaps he could mark this bug as a dup?
This comment fixed the problem for me: http://bugs.gentoo.org/show_bug.cgi?id=49277#c9 In particular, I commented out CONFIG_MODE_TT, then: # mv .config config # make ARCH=um distclean # cp config .config # make ARCH=um oldconfig (reject the static linking alternative) # make ARCH=um linux and it finally didn't get link errors...
