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.

Looks like that did the trick, thanks!
