Probably the usb drivers. I'd do what it suggests, and try rmmod'ing them before you suspend. Various suspend problems are being worked on in the FC5 tree. Eventually these will find their way back to FC4. In the meantime, if I were you, I'd look into using a script like pm-hibernate to put your system into a quiet state before it suspends.
I see the same problem with my ThinkPad T42. It's not USB, since removing usb_uhci before going to sleep doesn't solve the problem (although it solves other problems, like USB not working at all on wakeup): /sbin/modprobe -r usb_uhci echo -n mem > /sys/power/state /sbin/modprobe usb_uhci I've been looking around for pm-hibernate but can't find it (neither on my system nor out on the web). Anyone have a link to where I can get it?
Ah, here it is: http://gnome-power.sourceforge.net/
