MichalK Posted February 16, 2008 Share Posted February 16, 2008 Hi, After doing 10.5.2 udpate, my system refused to run with "Unable to find driver for this platform: \"ACPI\" kernel panic. Reverting the AppleACPIPlatform.kext to the old (non-vanilla) one did the job. However I'd like to be able to use vanilla one. What could be the problem? I'm running the E2180 on Asus P5LD2 (i945), PC EFI v8 and 10.5.2 vanilla kernel. Michal Link to comment Share on other sites More sharing options...
MichalK Posted February 16, 2008 Author Share Posted February 16, 2008 One more observation.. With the "-f" switch, the system boots fine. Michal Link to comment Share on other sites More sharing options...
MichalK Posted February 17, 2008 Author Share Posted February 17, 2008 Solved. After restoring bios defaults, AppleACPIPlatform 1.2.1 did not panic anymore. Strange thing is, I've started tweaking my BIOS settings one-by-one, to the state before restoring and guess - i cannot reproduce the panic anymore with my "old" settings...

MichalK Posted February 17, 2008 Author Share Posted February 17, 2008 So if i restore my bios settings i wont have to boot anymore with the -f bootflag ? In my case, it works. I'm clean booting, without the "-f" (nor any other) flag. Michal Link to comment Share on other sites More sharing options...
kilven Posted March 15, 2008 Share Posted March 15, 2008 it's because you didnt update the kext cache. when you booted with -f it was updated. permenantly. that's why you cant reproduce the error. it is fixed! Link to comment Share on other sites More sharing options...
