It's the same loop -- MILO also calculates bogos.  Unsurprisingly,
for use in the same delay loop that the kernel uses.

The problem is that the hardware clock has stopped ticking, so no
interrupts are ever delivered.  Nor, if you took the effort to do 
so, is the update-in-progress bit ever twiddling.  The clock is
really and truely stopped.

I do not know why this happens, but I've seen it on two machines.
