I get this screen when I updated from 10.5.5 (iATKO 5i) to 10.5.6 using software update.

I am using PF Bootloader, Stock ACPI, Kernel 9.5.0 fass, Default Decrypter...

I thought with those main options that the OS will be updateable?

I also remember getting that screen right after the initial bootup after installing iATKOS 5i for the first time. I had to reboot the computer several times and it solved the problem and I never got the kernel panic again. Not sure what went wrong.
