Sort of. You have to switch the console loglevel to at least 5 before suspend to see the messages. The kernel used to switch this to 10 unconditionally before and lots of debug garbage got printed, especially on -mm. We considered printing some "crucial" messages (like the progress meter ;-)) at KERN_CRIT, but decided not to do this for now. We can change this at any time, if needed. Greetings, Rafael
