Yes, I think any kind of xenconsoled hang can eventually result in guests
spinning waiting for their console buffers to be emptied. It might be
interesting to build xenconsoled with debug symbols (-g compile option) and
attach gdb when it gets in this state. Without that kind of info it'll be
hard to track down.
