Badness in futex_wait

Hi,

Don't now if this is useful or indicates any possible problems at all, but found this in kern.log:

Jan 20 18:33:30 horizon kernel: Badness in futex_wait at kernel/futex.c:509

2.5 days later machine hanged (but propably due to being nForce2 based).

Kernel version: 2.6.1-rc1-mm1
