Sure. Ingo has a script for gathering info (attached), if you run it, please gzip up the output and send me a copy offline to eyeball.
There's also ftrace, but I've not tried that yet, so can't offer any advice, I use primitive but effective time_after() + printk() with klogd wakeup disabled (deadlock).
