Comment 1 Jarod Wilson 2008-07-03 11:23:20 EDT
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 2008-07-09 23:56:00 EDT
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 12:31:21 EDT
Thanks, I picked up and everything is working now.
