<< Solved >> MacPro 5.1 Kernel Panic with Opencore Legacy Patcher... HELP

[fedepuli]

Hi, can someone help? I have a MacPro 4.1 updated with apple firmware to 5.1... I'm using opencore legacy for installing monterey since 4 days ago (you can immagine my mental status rn). I have no problem booting the installer or the post reboot install part but when is comes the main boot part of the completely installed system it just won't work... I have a sort of kernel panic and anything I did, didn't solve the problem. I also tried (with the same opencore efi, from the legacy patcher) different versions of mac os and it boot just with catalina. I really can't understand why.. I read on forums that a lot of people are using monterey on their Mac pro 5.1 with absolutely no problems... and obviously my Mac pro is supported by the patcher. Please help me... my hardware: MacPro 4.1 (upgraded to 5.1), Intel Xeon X5680, 64Gb 1333Mhz DDR3, Radeon RX 580 8Gb, Lexar 480Gb Sata SSD. I also have a usb 3.0 pci express card and a blackmagic intensity pro 4k (I tried booting without these 2 and makes no difference)

SOLVED!! They already told me to have a nvram reset but it didn't solve the problem... just for trying I did it multiple times untill the kernel panic disappear (3 nvram reset did the job for me)
