Freeze failures with F18

[William Murray]

   Dear all,
       F18 has been going well for me, but freezing my laptop stopped 
working 3 days ago.
Looking at my logs, the only rpm change on the 10th of Feb was 
installing ecj - I guess
it is unrelated. Anyway, from my first suspend on the 11th I got this:

Freezing of tasks failed after 20.01 seconds (1 tasks refusing to 
freeze, wq_busy=0):
  rmmod           D ffff8801be613cc0     0  1073    957 0x00000084

Suspend is REALLY useful....any ideas how to debug this?
      Thanks!
            Bill
