Hi

WARNING: at kernel/sched.c:4254 add_preempt_count+0x61/0x63()
Modules linked in: i2c_nforce2

Pid: 3620, comm: rtorrent Not tainted 2.6.26-rc8-next-20080704 #5

this warning is what triggers:

 #ifdef CONFIG_DEBUG_PREEMPT
         /*
          * Underflow?
          */
         if (DEBUG_LOCKS_WARN_ON((preempt_count() < 0)))
                 return;

i.e. preempt counter underflow. That can happen either due to unbalanced preempt_disable()/preempt_enable() pairs, or can happen due to stack overflow/corruption.

^--- POISON_INUSE

But I don't know if this is really significant, given that it's not the first error you're getting. It may also be just a remnant of the memset() that marks the SLUB objects as such. (Or something like that.)

Too bad the recursive page fault stops us from getting the Code: line.

Config would be nice :-)
