With exactly the same UML invocation, twice in a row, the first will panic: Kernel panic: Segfault with no mm In idle task - not syncing and the second will boot successfully. Even within an invocation, things aren't normal: sh-2.05a# apt-get source -b hello apt-get: error while loading shared libraries: /lib/libm.so.6: cannot read file data: Error 38 sh-2.05a# sh-2.05a# apt-get source -b hello Reading Package Lists... Done Building Dependency Tree... Done And of course, I haven't been able to get this to happen in the debugger (yet). -- - mdz ------------------------------------------------------- This SF.net email is sponsored by: IBM Linux Tutorials.
