msingh Posted September 18, 2009 Share Posted September 18, 2009 I have a problem on a retail install of Snow Leopard on D830: "No HPETs available...CPU(s) configured incorrectly ... AppleIntelCPUPowerManagement/...-90/pmThread.c:148 Upon reading that this can be caused by a faulty dsdt.aml, I did the following: 1. Used a Linux Live CD to get dsdt.aml from the laptop (cat /proc/acpi/dsdt > dsdt.aml). 2. Transferred this to the macbook. 3. Disassembled it. 4. Edited it to fix the RTC length 2. 5. Compiled it. 6. Gave me an error that *pnp0c14 had to be purely alphanumeric (line 7030). 7. Deleted the *. 8. This time it compiled correctly. 9. Copied this dsdt.aml to / and /Extra. I still get the same problem. Am I missing an /Extra kext ? I am attaching the original dsdt.aml obtained from the laptop using the linux live CD. And the edited dsdt.dsl that was used to generate the dsdt.aml used. I found this link: Fixing DSDT It requires fixing HPET, TMR and RTC. The motherboard in that link is different, but it suggests that I need to do something similar to fix the above problem. Can anyone help on this ? d830dsdt.aml.orig.zip dsdt.dsl.zip Link to comment Share on other sites More sharing options...

overflow1972 Posted September 18, 2009 Share Posted September 18, 2009 Hi, thanks for your guide. It's great. I have a question for you. I had the same problem on my usb stick to install snow on my Gigabyte GA-EP35-DS4. I had the HPET problem with a kernel panic on AppleIntelCPUPowerManagement kext. But I had NO DSDT file on the stick. And I had NO disabler.kext on the stick So do you think that this is the reason of this error ? What happen if I add disabler.kext (I am already using NullCPUPowerManagement.kext) ? ........or do I need this dsdt file (by using your guide) so I can delete the disabler kext ? Thanks Link to comment Share on other sites More sharing options...
