Default ssh sessions with pseudo terminal hang when in kernel events thread hangs

To follow this up (I only received one private reply so far), I've
filled bug #670398 with more information.

Short summary: I currently think it's an issue with Intel Nehalem CPUs.
So far we've evidence for the following CPUs (all Lynnfield as far as I know):
- X3430
- X3450
- L3426

In case someone experiences those issue on CPUs beyond the
3400 series I'd be interested to know about that.
