I've successfully installed 10.8.5 in my HP 630, audio, video, wifi, battery, all cpus worked fine using some kexts. The things I used are here. Everything was running smoothly. I yesterday installed Mavericks, and here, everything is working fine. The only issue I'm facing is - randomly system freezing, I cannot do anything without turning of the laptop. Console log is attached here. Please help me to sort out the issue. Thanks
