2.6.15-rc5-mm3 -- BUG: using smp_processor_id() in preemptible [00000001] code: swapper/1

[Miles Lane <miles.lane@gmail.com>]

Sorry, not sure who owns this code.

Here's something I don't remember seeing before.  Not sure if it is significant.

[4294669.070000] PCI: Bus #03 (-#06) may be hidden behind transparent

This is also new.

Anyhow, there are more, but I bet this is sufficient.
