[Bug 1426216] Re: pci driver messages - BAR 13: no space for
This appears to have been originally reported against a 3.18 based
kernel. We've since released 15.04 with a v3.19 based kernel. I'd be
interested to know if this is still an issue. I'll ask one of my
engineers with access to a Power8 system to see if they are able to
reproduce with our 15.04 release kernel. Thanks.
