I have a problem. UML(sys-kernel/usermode-sources) doesn't work and give me kernel panic. My logs is on forums(http://forums.gentoo.org/viewtopic-t-528247.html)
Don't refer to forums.g.o. when reporting bugs; it's just wasting everyone's time. Reopen once you've posted all the relevant info here. Thanks.
Ok. No problem.

Need to reopen, noone will notice again otherwise...
init segfaulted. This will cause a panic on any linux system. Can you loop-mount the device and run init? Can you boot it with init=/bin/bash on the command line?
6 months...
