I have a new MacPro that is having an intermittent issue. I ran it for almost a week without issue. Then last Friday it started to hang. Everything is fine and then all of a sudden everything becomes unresponsive except for the mouse. I can't click on anything, but the mouse moves. In a minute or so I get the SBBOD and my only recourse is to hard boot it.
I have looked at the console logs and a couple of times there was a GPU error, but not every time. I spent part of Friday night stressing the GPU and it did NOT fail. I talked to Apple as well as the people at the Applestore and they were willing to do a stress test, but I didn't want to be without the Mac that long and I really wasn't sure it was a GPU problem. So, I wiped it and did a clean install of Yosemite and I created my account, copied my files from a backup and manually reinstalled my apps. So it's about as clean as I can get it. I ran OK yesterday and today until just after 1 PM. Then the same thing happened. I think I am going to have Apple send me a new Mac since I am within the first 14 days of ownership, but I am posting the console log file here in case someone can see some other issue. If I have some software issue, then getting a new Mac will not solve the issue.
I have included some of the log that came before the hang, but my clock stopped working at 1:03.
Any insight is greatly appreciated.
