Comment 1 Jarod Wilson 2008-07-03 15:23:20 UTC
Crap. I'll have to double-check, perhaps I stupidly didn't actually port the change over to the F8 kernel 

Comment 2 Jarod Wilson 2008-07-10 03:56:00 UTC
Yep, the updated patch in F9 never actually made it into the F8 branch. Just
committed the changes in kernel though.

Comment 3 Scott Dodson 2008-07-12 16:31:21 UTC
Thanks, I picked up and everything is working now.
