Rawhide (today) -- Repeated I/O lockups forcing me to power cycle my laptop

Hello,

I haven't been able to determine a pattern to these lockups.  Mostly,
they seem to happen when the machine is idle.  I don't know if they
were related to running xscreensaver.  Maybe there was some connection
to a 3D screensaver?  I am running SELinux enforced.  The most recent
lockup seemed to come gradually.  My mouse became more and more
unresponsive, but "top" did not show any process hogging the CPU.  I
probably should have checked memory consumption, but I forgot.  I
don't recall the hard drive thrashing.  Also, background processes
continued running happily (the clock applet, the system monitor
applet, etc).
I did notice in one of the logs today, the following:
