Comment 23 for bug 651370

Stefan: the ~32 vs ~64GB memory issue is very likely orthogonal and has a separate bug now (bug 667796). This issue is solely about intel_idle vs certain CPU types under Amazon's EC2 (Xen) environment. m2.4xlarge in us-east reproduces the crash on boot readily (and also happens to exhibit the memory limit issue), and c1.xlarge reproduces it some of the time (depending which hardware you are randomly assigned).
