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?
the only thing i did differently to you was to run nullCPUPower.kext or whatever it's called in Multibeast... i did that a few days after i had my 10.9.1 install settled though... perhaps that helps. I installed the one for Sandybridge... even though after reading it said it was only for gigabyte mobos! oops. But as i say, mine went fine :/
