H77 updated to 10.15, kernel panics immediately on boot

[TheBloke]

System: H77, Core i5-3550. AMD Vega 64 8GB GPU. iMacPro 1.1 SMBIOS.

I was running 10.14.6 Mojave no problems. Two weeks ago I tried Catalina beta6, and it upgraded and worked fine. Later I tried to upgrade to beta 10, and after rebooting I got KP immediately on boot.

Today I tried a fresh upgrade: I cloned 10.14.6 Mojave install to new SSD, booted 10.14.6 install to confirm 100% working, and also removed all 32bit apps. Then tried 10.15 upgrade from App Store.

Upgrade seemed to run fine, but again I get KP almost immediately on first reboot.

Clover is 5070 UEFI. All kexts should be latest version. I have tried booting Clover without any injected Kexts, and KP happens exactly the same.

DSDT was previously patched by mald0n last year and I think is OK.

I have tested with both SMBIOS iMacPro 1.1 and iMac 14.2.

Here are my RunMe! files, taken from working 10.14.6 install. I cannot boot into the 10.15 install to show logs from that. Send me H77-Marv.tom.tj.2019-10-11.zip

 

Thanks very much in advance for any help.

[ref]MaLd0n[/ref], thanks for the fast reply.

Unfortunately, no change. Upgraded to Clover 5096, and tried booting with no DSDT.aml, and the same KP happens at the same point.

I tried making a video of the boot logs. It is hard because it scrolls so fast, but I got a very rough video frame capture from around the time it crashes:

From this I can see:

1. It is a Kernel trap / page fault

2. There is some message right before it, " trying to set protected key "FM..something". It is hard to make out. I don't know if it's relevant.

3. The KP happens right after or during the loading of FakeSMC. Maybe this is significant.

I am using the Rehabman/kozlex FakeSMC, last updated September 2018.

I already tried booting with all FakeSMC kexts not injected, except for FakeSMC.kext itself. But perhaps this particular FakeSMC has problems with latest Catalina?

After dinner I will try another FakeSMC, like VirtualSMC. Is there any particular FakeSMC that you recommend?

Thanks again.

[ref]TheBloke[/ref], try with Olarila folder

I finally solved it Issue still happened with VirtualSMC, and when using the CLOVER.SERIES.CHIPSET.

I took some more videos of the kernel panic log, and saw there were references to AHCI, and to the version number 999.1.1, which I vaguely remembered from a while ago.

Answer: It was the AppleAHCIPort.kext from InsanelyMac, that I had installed 1-2 years ago! It was still in /Library/Extensions.

I don't even remember why I installed it in 2018, but I don't need it any more on either of my Hacks, so I have removed it.

I had to re-clone a 10.14.6 install onto the SSD and then re-install Catalina, because just deleting the .kext from the Catalina /Library/Extensions did not solve the problem. I guess it was still cached somewhere. But once I removed it from 10.14.6 then cloned and did the Catalina upgrade, it installed and rebooted fine.

Lesson: when doing upgrades, check what random kexts are still installed from years ago, and remove any you no longer need!

Thanks for the replies mald0n, as always.

[ref]TheBloke[/ref], k

i'll update folders and back to fakesmc, i prefer btw

[TheBloke]

Yes, on my two systems I get more info from FakeSMC than with VirtualSMC, which is why I have never moved on from FakeSMC even though it is now 1+ years since last update.

the Slice version is very nice
