Looks like your system is confused.  I suspect whatever kernel you are
running has a bug in the vm code.  That number is most likely
-13468 bytes since that is how far it is from 2^32.  So something got
confused.  Time to reboot and most likely time to go find a less bugger
kernel version.  If it's a recent kernel version, report it to lkml too
if you can gather any info on how it happend (what system was doing,
uptime, etc).
