KUEP broken on FSP2?

Hi, I'm attempting to run linux 6.1 on my FSP2, but my kernel crashes attempting to get into userspace. The init script works, but the first binary (mount) I run results in oops. Can anyone help me to debug this further or suggest anything? Thanks, Eddie [    1.042743] kernel tried to ex

PPC476 hangs during tlb flush after calling /init in crash kernel with linux 5.4+

Hi all, I'm having a problem in simulation and hardware where my PPC476 processor stops executing instructions after callling /init. In my case this is a bash script. The code descends to flush the TLB, and somewhere in the loop in _tlbil_pid, the PC goes to InstructionTLBError47x but does not go
