For me this command doesn't produce any output. Also, no output from the
command Kim used in response to you. With no `grep` it just dumps a
table of raw hex data.
It's `msr-tools` 1.3-4 from Arch. Should I run this command on a patched
kernel booted with `no_parallel_bringup`, or on unpatched kernel (if
that makes any difference)?
