Has anyone had any luck getting F17 to install on a 7r2? When it boots from the yaboot (on the graphical console) it gets to a screen where it says "Performing OPAL takeover" Then the screen goes blank. I finally figured out that it switched to the serial console, where I saw it start to scroll through the installer boot-up, then it said unsupported arch type ppc. Any ideas? Are there any boot args I can use to get past this?

Re: Fedora 17 on 7r22012-07-06T22:13:26Z in response to tjacks55This is not a bootloader problem. From what I can tell:- The machine is a pre-IOC 730-L, it has OPAL v1 "takeover" support- The kernel has been compiled with the PowerNV platform support enabled (OPAL platforms)The kernel attempts to do an OPAL takeover .. and succeeds. On the other hand, it looks likethe fedora installer doesn't recognize the resulting platform.There is no way to prevent the takeover attempt without rebuilding the kernel without PowerNVsupport, though I could cook up a patch, we might want to disconnect the general PowerNV/OPALsupport from the takeover functionality on OPAL v1 and keep a way to disable the later at buildtime or something...

Re: Fedora 17 on 7r22012-07-09T12:39:07Z in response to tjacks55Let's start simpler and rule out any easy stuff. Can you you paste the sha256sum of your media (or md5sum if you prefer)?Then, you mention you are able to switch over to serial, what command args are you using to do this? And finally, have you tried to pass the vnc argument to force a VNC-based graphical install?Many of us hang out on #fedora-ppc on freenode if you would like to swing into there, perhaps we could help you out a little more interactively.Brent

Re: Fedora 17 on 7r22012-07-09T17:36:43Z in response to tjacks55I was able to install Fedora17 GA into an LPAR on a 7r2. Seeing that you are running into PowerNV issues though probably means you are not using virtualization. Do you have the latest firmware on your machine?For me, vnc mode didn't seem to work out of the box - the network manager never asked for an IP address so when the VNC server came up and looked for an IP, it would fail. I just did an old text mode install, which completed ok. I never saw any PowerNV/OPAL issues...

The 'fedora installer doesn't recognize..' statement keyed off the initial statement:tjacks55> ... then it said unsupported arch type ppc.Are there any Fedora debug parms to throw at this to help determine the what/why it decided ppc arch type is unsupported?

Re: Fedora 17 on 7r22012-07-10T14:33:57Z in response to willschmThat's correct, it does the takeover just fine I think (assign from changing my default console from graphic to serial) It's on the fedora installer that it hands up with the unsupported architecture type. I don't know if it matters, but the hardware is actually the L2B pre-prod version of the 7r2, not the released L2C. Which I believe the IO/PCIe is different.
