Bah, I always need to write an email to reproduce that. It's back:
3.7.0-rc7-next-20121130
[<ffffffff810b132a>] __cond_resched+0x2a/0x40
[<ffffffff81133770>] shrink_slab+0x1c0/0x2d0
[<ffffffff8113668d>] kswapd+0x65d/0xb50
[<ffffffff810a37b0>] kthread+0xc0/0xd0
[<ffffffff816ba4dc>] ret_from_fork+0x7c/0xb0
[<ffffffffffffffff>] 0xffffffffffffffff
Going to apply this:
https://lkml.org/lkml/2012/12/3/407
and wait another 5 days to see the results...
thanks,
