Hi Ingo, CC'ed Steven Rostedt
I found the following patch cause regression by bisect.
2.6.25-rc2-mm1: doesn't boot 2.6.25-rc2-mm1 + revert following patch: works well
but I think it is very strange. runqueue_is_locked() seems simple and have not bug. ;)
What do you think this problem?

printk: dont wake up klogd with the rq locked
It is not wise to place a printk where the runqueue lock is held.
