I still get
ipmi0: sendcmd failed
On various other machines, when ipmi is enabled. Not right away, but
eventually.
The problem isn't that there are machines with busted IPMI, it is that
our ipmi code is incredibly optimistic and doesn't know how to cope with
failure.
And as a result, the ipmi code will remain disabled until someone steps up
and makes the code better. Having a few more sensors does not justify the
potential problems.
