With linux-headers-2.6.20 or greater, and vanilla-sources-2.6.22-rc4, here's what I get when I do a "make linux ARCH=um". When I use  linux-headers-2.6.19,2-r2, this problem goes away and UML builds and runs just fine.

This is a known issue with UML.  It's fixed in usermode-sources-2.6.18-r2, but the fix has not yet gone upstream.  One of the patches was submitted for 2.6.22
