Description (last modified by )
I was doing a "strace -s CDPlayer" in Terminal and pressed the keys to enter KDL. The white ribbon appeared but no text, and input wasn't possible. I also had ActivityMonitor running. Revision should be around hrev35383. This is on a quad core.

I've seen the problem, too. Though not on voluntarily entering KDL, but on a panic() (at least I think it was a panic() -- I had no serial port at that time). Can you reproduce the bug with the described method or was that a one time thing?
Regarding _kern_port_buffer_size_etc(): That's a blocking call (it waits for new messages).
