kernel BUG at lib/kernel_lock.c:83! - 2.6.19-1.2895.fc6

Hello,

Kernel 2.6.19.x seems much more stable in my setup than the previous 
versions 2.6.18/17.x which used to lock-up 5 times a day.

I did get the following crash last night (forgot exactly what I was 
doing - killed rsync server), I just saved the error and rebooted.

I found a similar error here:

    http://lkml.org/lkml/2005/8/19/70

but this was posted more than a year ago ?

Albert.
