Running tests with latest current locked up my machine:

kernel/t_umountstress (91/764): 2 test cases
    fileop: [0.994189s] Passed.
    mountlist: 

No more output on that session, but console was still responsive.
I could not log in though, the login process hangs after logging the log in
to syslog.
