sleeping function called from invalid context

[Samuel Flory]

 I'm seeing this on arjanv's 2.6.0-0.test4.1.33 kernel.

Debug: sleeping function called from invalid context at 
include/asm/uaccess.h:473
Call Trace:
[<c011b7dd>] __might_sleep+0x5d/0x70

 Any thoughts.  The system seems to function despite the issue.  It 
seems to have also occurred under 2.6.0-0.test3.1.31:
