ACPI PCC Probe Failed is the error that pops up instead of the default GRUB loader after I updated my kernel to 3.19.



I searched around and couldn't find much information except that it is a known error and it is registered in kernel.org's launchpad https://bugzilla.kernel.org/show_bug.cgi?id=92551. My question is, is anyone else facing it?, what are the impacts of this? And if only an update in the future can fix it, any suggestions or safety tips till then?

Apparently it is a harmless message related to a 'PCC' driver:




So it looks like you build the PCC mailbox driver which is new in 3.19-rc and
that driver fails to load, because it doesn't find hardware to work with.



The message is harmless, but it also is not useful. The driver in question
seems to be overly verbose to me in general.




That is what I gleaned from this conversation.
