I'm seeing this while going into suspend:

Looks like it was a known problem (sorry about the noise), see:
http://lkml.org/lkml/2007/8/25/117
It does fix the problem here as well.
Ingo: is this still the right fix for 2.6.22.6 + rt9?

It should print what went wrong about ~20 seconds. If it does not, verify that timers work properly for you.

Hi! Hi Ingo... I'm getting reports from some of my Planet CCRMA users (which I confirmed) that the latest rt kernel I released has broken suspend (tested on fc6 fc7, stock Fedora kernel works fine - the rt configuration files are virtual clones as far as possible of the standard Fedora kernel config files). I don't know where to start debugging this. When suspend is initiated it freezes with a Stopping tasks ... message in the text console - a hard power cycle is the only way to get the machine back to normal. It should print what went wrong about ~20 seconds. If it does not, verify that timers work properly for you.
