Re: Bug#705435: [kfreebsd] hangs on pulseaudio --start
So far as I can tell, this bug is a race condition; on one machine I
can reproduce it about 75% of the time, less often under ktrace, and
never under gdb. During gdm3/GNOME startup it is called several times
and almost certainly means a non-starting session.
Sometimes it prints 'Daemon startup fails' before the hang, and
sometimes it does not.
I think it hangs within the lock-autospawn code, for synchronisation
between threads. I think if one of the threads is suspended, it does
not resume, and so the other one waits for it indefinitely. This may be
a quirk of kFreeBSD's threads implementation, or may happen if a signal
is being masked that should not be.
