With UML kernel 3.7.10 (host kernel still 3.8.4) I can trigger this
issue too.
Just to clarify it - here the bug appears in the UML kernel - the host
kernel is ok (I can of course crash a host kernel too by trinity'ing an
UML guest, but that's another thread - see [1])
FWIW he trinity command is just a test of 1 syscall:
$> trinity --children 1 --victims /mnt/nfs/n22/victims -c mremap
