fedora 18 /var/log/messages filling up but I can't find the cause
I've recently upgraded to Fedora 18 (w/KDE desktop) on a dual boot Dell laptop (I'm still a Linux newbie and I'm also running Vista) and the /var/log/messages file is filling up slowly to the point that it fills the / dir. I don't understand what program or process is writing to the /var/log/messages file and causing it to balloon into an unmanageable size. A few sample outputs from this file are contained below.
Mar 16 03:49:11 localhost kernel: [ 28.410716] whci-hcd 0000:0d:00.0-1: wusbhc_rh_suspend (ffff88020dc19800 [ffff88020dc19800]) UNIMPLEMENTED
Mar 16 03:49:11 localhost systemd[1]: Started Replay Read-Ahead Data.
Mar 16 03:49:11 localhost kernel: [ 28.410738] whci-hcd 0000:0d:00.0-1: wusbhc_rh_suspend (ffff88020dc19800 [ffff88020dc19800]) UNIMPLEMENTED
etc...
When I shutdown I get the same error written repeatedly to the screen forcing me to do a hard shutdown each time. Upon rebooting the / dir starts back at 22% use (from a df -h or -m command) and slowly increases from there. I can't figure out what process or program is writing to this file so I can't even begin to correct it. The message seems to indicate a problem with the kernel but I don't have enough experience to diagnose and trouble shoot it.
In case it matters, I have configured machine to run CUDA so I've replaced the Noveau drivers and only installed some computational programs like Matlab, octave, etc. The system is otherwise unmodified.
Any help would be greatly appreciated as I'd like to not have to switch to a different distribution.
