Sense: Not ready to ready change, medium may have changed I got a lot of those messages. It was logged every 5 seconds. It stared when I plug a music player to usb, but it "works" with simple 1 gig memory, too.
Sorry, my mistake. Problem is with my music player (some older version of http://www.sony.co.in/product/nwz-b153f) and it is constant. Every time I plug it, I'm spammed by those messages. Every time I unplug it, I have X server crashed. I always can start it again without reboot, but it's a bit annoying.
Could you please try this update and see if the problems recreate: https://admin.fedoraproject.org/updates/kernel-2.6.40.6-0.fc15 There have been a few USB drive issues that are fixed here. Also, if it is really the X server that is crashing and not the kernel, you might want to reassign this to the xorg-x11-server component.
I completely forgot about this request, sorry. It's working since a while. I really don't know why, or how, but yeah... It works.
