I haven't tried to track this down yet, but with recent 2.6.16-git, it
seems that the suspend console is gone... That is, the kernel still
switches VTs from X to some console with no getty on it, but no kernel
message gets displayed at all during the suspend process... looks like
this kmsg_redirect thing isn't working.

Known problem ?

Ben.

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
