supermuffie Posted August 10, 2015 Share Posted August 10, 2015 Hi everyone, first of all I´d like to say “Hi” to everyone, as this is my first post on here. For a couple of days, I´ve been trying to install Yosemite 10.10.4 on the following system: HP z820 Ivy-Bridge-EP Dual Xeon 2643v2 3.5GHz 64BG (8x8) PC3 14900R @ 1866Mhz ECC Buffered Samsung 845DC Pro 400GB on AHCI #0 EVGA GTX 750 HP Thunderbolt Option Installed 1125W PSU HP Liquid Cooling with both Clover and Chameleon, tried different USB Drives as well. Whatever I do, the system get´s stuck with a ACPI CPU kernel panic, which is literally telling me that my 13th core on my 12 core system is messing about, ugh haha I´ve tried all possible boot arguments, different plist.config files, messed about with all possible BIOS settings. Tried Clover UEFI & legacy bootloaders, and never got past the kp as seen in my attachment. I´m losing faith, especially as I´ve made quite some effort to gather all info available on the web, regarding this Hardware ( HP z820 ), and have taken all of that into account in one attempt or another. No one else seems to have had this kind of trouble so far….any help would be much appreciated. Jules 1 Link to comment Share on other sites More sharing options...
vusun123 Posted August 10, 2015 Share Posted August 10, 2015 Disable HyperThread first to avoid those nasty AppleACPIPlatform panic, or use a patched one 1 Link to comment Share on other sites More sharing options...
supermuffie Posted August 10, 2015 Author Share Posted August 10, 2015 hi mate, thanks for the quick reply. i´ve tried that, and the only difference it makes it that the kernel spits out 7 instead of 6 cores...then panics. any suggestions? edit: i´m using NullCPUPowerManagement.kext as well...

Somewhere in this forum, there's a patched AppleACPIPlatform to avoid this kind of panic Link to comment Share on other sites More sharing options...

jl4c Posted August 10, 2015 Share Posted August 10, 2015 Disable VT-d in Bios or use dart=0 boot flag. Link to comment Share on other sites More sharing options...
supermuffie Posted August 11, 2015 Author Share Posted August 11, 2015 Nothing´s changed. Vtx is disabled, etc pp. Please excuse my stupidity, but I´m assuming that Clover isn´t loading the extra .kexts at all. I put them into the 10.10 folder on the USB drive. I don´t really know what path to put into ForceKextsToLoad...pls advise on this. Many thanks! It now says: Refusing new kext com.apple.driver.AppleACPIPlatform, 9.9: already have prelinked v.3.1 Link to comment Share on other sites More sharing options...
supermuffie Posted August 11, 2015 Author Share Posted August 11, 2015 I´ve tried, but this is giving me the kernel panic described in my initial post > see screen. I have the impression that all this has to do with my BIOS settings...what a head{censored} :/ Link to comment Share on other sites More sharing options...

bobjones16 Posted September 28, 2015 Share Posted September 28, 2015 hey supermuffie, I have a very similar set up as you and just cannot get Clover to the point of installing Yosemite. Have you had any success? Link to comment Share on other sites More sharing options...
