This doesn't sound like "a minor bug" ?

What are the actual symptoms of the bug? Does it crash, always, sometimes? Does
it actually "block the subsequent ipmi operations"?

Even if this *is* a minor bug, please give it a proper subject that describes
what it does.

Also which commit introduced the bug?

And finally you don't seem to have CC'ed the ipmi maintainers?

cheers
