[Bug 651370] Re: ec2 kernel crash invalid opcode 0000 [#1]

[Brandon Black]

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).
