I can reproduce the bug. It is most certainly related to system call
restarting, but I am not quite sure of what happens yet. My BUG_ON
trigs, but I do not understand why, and the reason of the BUG_ON is not
what causes the -ENOSYS. I can not really use the I-pipe tracer, because
everything happens in assembly code with very few function calls.

So, it may be a while before I produce a fix.
