OK I have been racking my brains here with many different compiles and
hosts trying to get UML to run from a self compiled image.
I have used the 2.6.14-bs2 with both the configs of my own and the
binaries from the pre-built kernels
I have downloaded blaisorblade UML kernel binaries and they at least run
as expected.
Any kernels I have compiled myself do just kick off with segfault you
can't even get it to do --showconfig.
The kernel logs get this:
kernel: linux[31492]: segfault at fffffffffff00040 rip 00000000601951c2
rsp 00007fffffa94be0 error 4
Now here is my environment I am compiling with
For the AMD64 box and x86 Pentium IV box the systems are the same Debian
sid gcc 4 and I have used 3.4 gcc. Both kernels are SMP and I have
tested on vmware on a non smp configuration.

It has to be some how the build environment if I can run the pre-built
kernels, but I am not sure what to look for. I have moved the tls
modules out during compile thinking that there was some static linking
going on but it did not change.
If any more info would be needed please let me know.. the build configs
have been from the pre-built kernels as well as my own.
Thanks
