I've seen all manner of problems booting Linux guests since changesets 13115 (add HPET support), 13097 and 13096 (various changes to HVM platform timer support). With luck there have been just one or two issues introduced that are causing all these problems, but we'll have to throw out those patches if the situation doesn't improve in the next week.

Xiaowei: I'm pretty sure I can eyeball bugs in the new vpt.c code. For example, how can it be right that last_plt_gtime is incremented by period in some places and period_cycles in others? The two quantities have different units!
