Problem Description:

On boot, I get the following in dmesg and the console output:

INFO: possible circular locking dependency detected

Boot still runs to completion and machine still appears responsive, so this is
low priority. But this might point to a more subtle problem.

Steps to reproduce:
Compile 2.6.29-rc3 with fedora 10 and lock checking
Boot with vga=0x317 for vesafb
