SOS! Got this weird messages when doing the Mavericks post-installation

[soyasoo]

Hi guys, I faced this problem for few times when I kept trying the post-installation.

I'm using Gigabyte GA-Z97X-UD7 TH, i7 4790k, EVGA GeForce GTX760... Tried few times but still stuck with this part...



Here's the log in text version:

Try booting with the boot flag "cpus-1", as your KP is occuring in CPU core 4... Also see if you can boot in safe mode "-x"...

Cheers!

Thanks for your help!!! It works and i added npci=0x3000 as well... Can I know why is this message showed up?

Anyway, now i did not complete the post-installation but restore data/info from my time machine. Can I know what will happen by doing this? What is the risk too?

Thanks!!!

I have no idea why the message showed up, but it usually shows up because OS X has a problem with running multiple cores on some processors, so you need to direct all the computing to one core "cpus=1", and are you sure you need npci=0x3000? It's generally not recommended to have these kinds of boot flags...

I'm not really sure what will happen if you restore w/ TM as I've never done it before, but I generally don't like restoring an ENTIRE system from TM. I would do a full install / post-install, then restore all of your data, not system files, so that you know you're system's gonna boot up again.

Cheers!
