Hi! Back when I was in ubuntu maverick I compiled a 2.6.38.3 UML kernel and was able to use it successfully. I'm working on developing a kernel module. Due to a problem I flated gto ound during the development of the driver I saw myself in the need to recompile the kernel after upgrading to natty (don't know if this is related to the problem). I recompiled the kernel with the old .config and it stared to fail every single time with an abort signal. I removed the whole kernel and replaced it from scratch and redid the whole compiation process but it still fails. What's the meaning of this abortion onUMLs boot time:
