Ahem. Obviously, I skipped a step. Those config entries (and the build process I was describing) are a cut and paste from my build process that uses UML to build a uclibc against more recent kernel headers that the host kernel it's running under (which would otherwise tend to cause segfaults). That uses tt mode. If I do what I just described, the result works just fine, but it's in tt mode. Which is odd, because stock 2.6.12.2 does NOT work for me in tt mode: it goes: Checking PROT_EXEC mmap in /tmp...OK tracing thread pid = 11687 And then exits with no further explanation or printout. (I get my shell prompt back but it's the host system's shell prompt.) But with Blaisorblade's -skas0 patch, tt mode works. (Go figure.) However, the point of the patch is to try -skas0 mode, so I went in to "make ARCH=um menuconfig", switched off tt mode, and switched on skas mode. (I did this instead of oldconfig.) Then I got the trace from last message. Sorry for the confusion.
