macosxbootloader system_profiler SPPCIDataType crashes

I am using this boot loader on a MacPro1,1 and when /usr/sbin/system_profiler tries to list the SPPCIDataType data type, the program crashes. No idea if that is related to the bootloader or not ...

Uhm. You are the first person to report this, here, so I wonder why nobody else did before you. Perhaps something went wrong during the installation of Yosemite, and when I see errors like this, then I normally reinstall the OS.

Have you asked other people on macrumors.com if they are experiencing the same (kind of) error(s)?

I have posted it on macrumors, but nobody else seems to have seen it, or noticed it. I have a vanilla, new install of Yosemite on a USB disk done on a MacBook Pro, then changed the boot.efi, and the same thing happens when I boot my MacPro from there.

I believe this error is normal with an unrecognized PCIe card in the system. Are you using a non-flashed PC graphics card?

Oct 26 '14 03:10 MrZarniwoop

Yes indeed, I am. An NVIDIA GForce GT 640

Oct 26 '14 03:10 jamgold

Pretty sure that'll do it. To know for sure, if you have one replace with any EBC firmware Mac graphics card and I bet the error goes away and System Information will properly show PCI information. I think this is true even if there is no driver for the card, like an Nvidia 7300GT or ATI 1900XT.

Oct 26 '14 03:10 MrZarniwoop

I only have the original this 2006 MacPro came with. I thought it is not longer supported.

Oct 26 '14 03:10 jamgold

Correct, it'll be awful because Yosemite will have no driver. But, the PCIe card should be recognized and then you'll know it's not because of a bug in the boot loader.
