Hi All,

I have seen huge amount of message in the logs with the following pattern:

Oct 8 13:05:30 x kernel: WQ on CPU4, prefer CPU0
Oct 8 13:05:30 x kernel: WQ on CPU2, prefer CPU1
Oct 8 13:05:30 x kernel: WQ on CPU5, prefer CPU2
Oct 8 13:05:30 x kernel: WQ on CPU6, prefer CPU3
Oct 8 13:05:30 x kernel: WQ on CPU6, prefer CPU5
Oct 8 13:05:30 x kernel: WQ on CPU1, prefer CPU7
Oct 8 13:05:30 x kernel: WQ on CPU4, prefer CPU0
Oct 8 13:05:30 x kernel: WQ on CPU6, prefer CPU1
Oct 8 13:05:30 x kernel: WQ on CPU6, prefer CPU2

Any idea?

I see those whenever I try profiling with oprofile. I'm currently trying to nail down a routing performance problem, and those messages get in the way.
