3/1/2014: Tried to upgrade to 10.9.2 and failed
follow OS message to reboot and install the update, screen stuck at around 98%, had to use the power button to reboot the machine, got kernel panic:
kernel extensions in backtrace com.apple.driver.appleintelcpupowermanagement
none of the Cimera boot option helps, tried -f -x, etc.
reboot using my original mavericks install USB drive, F12 to boot from the usb, in chimera chose the installation drive, enter into the OSX installation screen, choose the language, then got access to terminal.
In terminal, go to S/L/E (System/Library/Extension, did "mv AppleIntelCPUPowerManagermentClient.kext to AppleIntelCPUPowerManagermentClient.kext.bak") and "mv AppleIntelCPUPowerManagerment.kext to AppleIntelCPUPowerManagerment.kext.bak")
repaired the permission, reboot, kernel panic at exactly the same location.
don't know how to solve this, so used the original OS usb drive to reinstall the system, took about 20 minutes, everything is back to normal.
anybody successfully updated their maverick to 10.9.2 on a XPS 8300?
