During bootup, I now have 162 messages like this..
[ 0.227346] MSR0000001b: 00000000fee00900
[ 0.227465] MSR00000021: 0000000000000001
[ 0.227584] MSR0000002a: 00000000c1c81400
commit 21c3fcf3e39353d4f21d50e257cc74f3204b1988 looks suspect.
It claims that it will only print these out if show_msr= is passed,
but that doesn't seem to be the case.
