Unfortunately, I can't seem to find a system call that reproducibly fails.
There's something weird and racy going on.  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).
