I've compiled UML kernel 220.127.116.11-bs2 using the 2.6.14 source and the bs2 patch from BlaisorBlade's site. The compile was clean, but when I run it, it seg faults without any delay:
I am running Debian 2.4.27 with skas patch on the host. I am using the same UML config as the 2.6.14-bs2 UML binary from BlaisorBlade's site. Incidentally, the downloaded binary runs just fine, as far as I can tell. I have tried both gcc 3.3.6 and gcc 4.0 compilers.
