    Dell Precision 5820 - Xeon w2125

    Help with Big Sur (11.6.0) on Dell 5820-X

    So, after using your EFI I have a karnel panic witch IONVMeController. I removed the Dell PCi-e 2x NVME 3.0 x4 023PX6 0NTRCY adapter and it appeared to my eyes. So what is the cause? Adapter or NVMe drive (PC601 NVMe SK hynix)?

    Without the disk and adapter, the installation stops there. Is the drive or the adapter to blame?
