Btw, you can also download pre-built UML binaries from my homepage (see

of months ago the answer was "let's blame this GCC", but this story is now
old).

that binary work, your one doesn't, let's compare configurations! Or a couple

sorry, I've been building cusom kernels too long. it never occured to me to download a kernel from anywhere else (even distro kernels are only on my machines long enough to install, download the latest kernel.org source, and recompile. and that's assuming I don't have a kernel sitting ready from another box :-)

useing your kernel uml-release-2.6.15.5-bb4.tar.bz2 I am able to boot, useing my kernel (config attached) I get the error "remove_umid_dir - actually_do_remove failed with err = -2"

working to decrease the diff between the configs I've generated a new config (attached) which has the same result.

< CONFIG_3_LEVEL_PGTABLES=y
< CONFIG_BLK_DEV_NBD=y

stripping out comments and modules (since I can boot your kernel with no modules available to it) I come up with the following differences in the configs (< is my config ) my config is for 2.6.16 while yours is 2.6.15.5 so some of the differences are due to the version skew.
