Same here ... the crashes started with 2.2.1, and continue through 2.2.2pre2 (which is currently running).

The mhz are read off the system board/cpu, where-as the bogomips are an actual 'rough' estimate of the cpu speed using a simple loop test (and should not be used for 'actual' benchmarkin :)

Well, if it helps, here's my config (sorry for the bandwidth usage =)
