For some months now I had a fully working machine, which was backed up with SuperDuper! every night to a bootable external drive before I went to bed.
Recently I wanted to start the machine and this came up:
panic(cpu 0 caller 0x2e8395ed):"i386_pmGetDeadline:NULL pointer\n"@/SourceCache/AppleIntelCPUPowerManagement/ApplIntelCPUPowerManagement-105.13/pmDispatch.c:130
It seemed the machine could not be started at all. I thought: " No fear, I have a backup, don't I?" The problem must have developed before I made the backup, so when I tried to boot the external drive to do a restore I got exactly the same message from the backup disk. I backed up the problem as well.
Fortunately on a separate hard disk I have Windows 7 installed so I could start to investigate on the net what caused this error. It seems other people have encountered this, as there were numerous entries about it. There were solutions to just delete this particular kext, (com.Apple.driver.AppleIntelCPUPowerManagement) something else here and there, but none of the offered solutions worked. Some of the solutions reckon it's caused by faulty RAM. I really thought this is IT, since recently I have bought another 4GB of RAM, so I removed it. Of course there was no difference. This was a dead end, since Windows 7 and Windows XP on yet another HDD work faultlessly. So, what to do, as my machine was set up real nice and I'd like to have it back?
I reinstalled OS X on the now defunct disk, and everything went smoothly, it boots with the Multibeast menu so I can choose the Win7 disk or OS X, which further proves the KP is not caused by RAM fault.
So, I appeal to anyone who had this problem AND SOLVED IT to share his knowledge with me. I would dearly have my machine work the way it did before.
