<< Solved >> Help with constant KPs

[manano]

Hardware:

• MB: GIGABYTE Z390 I AORUS PRO WIFI LGA
• CPU: Intel Core i7 9th Gen - Core i7-9700K Coffee Lake 8-Core 3.6 GHz
• RAM: Corsair Vengeance LPX 32GB (2x16GB) 3200MHz C16 DDR4 DRAM
• Storage: WD_BLACK 1TB SN750 NVMe
• GPU: SAPPHIRE Radeon 11265-05-20G Pulse RX 580
• Clover Bootloader - 5136

I have a build with the above hardware and it has very stable for the past year, but recently I am having constant Kernel Panics.

The KPs seems to happen most often when the OS has loaded and I log in. Either before my profile loads or later when apps start up. The other times it crashes is as it is loading the OS and it seemsto be very very slow. I have looked at the Clover bootlogs and have not seen any errors.

I tried doing a reinstall of the OS through recovery mode, in case it was some OS corruption, but the recovery is stuck on Examining Volumes and it never returns (even after over 1/2 hour)

The only consistent clue I have is the following error

panic(cpu 0 caller 0xffffff8005d86d06): nvme: "Fatal error occurred. CSTS=0x3 US[1]=0x0 US[0]=0xda VID=0x15b7 DID=0x5006

I have tried updating the NVMeFix.kext and still it crashes 8 out of 10 times I turn my machine on.

From the error, it seems like there might be a problem with the NVMe but I am not sure what I can do to diagnose it further.

Any thoughts or help would be greatly appreciated

Had to reinstall but even that was very painful.

• Reinstall would always freeze at Less than one minute remaining
• Recovery would not recognize wired keyboard/mouse after initial reinstall
  • Realized that USBInjectAll.kext was problematic so I removed it from my [I]EFI/Clover/kexts/other[/I] folder
• Reviewed BIOS settings, even though no changes had been made since initial installation
  • Followed instructions to set BIOS
  • Installation completed
• Ensured that the xhciportlimit quirk was set to false in my config.plist
• Completed reinstall
• Migrated my files from TimeMachine
