# Analyze Kernel Oops Use `scripts/debug/memdump.py` to extract and analyze the Oops. ## Steps 1. Extract the Oops: ``` python3 scripts/debug/memdump.py oops ${ARGUMENTS:-memdump_jit.bin} ``` 2. Decode pt_regs (use the REGS address from the Oops output): ``` python3 scripts/debug/memdump.py regs DUMP_FILE REGS_ADDRESS ``` 3. Disassemble around NIP and LR (convert VA to PA: PA = VA - 0xC0000000): ``` python3 scripts/debug/disasm_ppc.py DUMP_FILE PA_OF_NIP 16 python3 scripts/debug/disasm_ppc.py DUMP_FILE PA_OF_LR 16 ``` 4. Search for the NIP value in both dumps: ``` python3 scripts/debug/memdump.py find memdump_generic.bin NIP_VALUE python3 scripts/debug/memdump.py find memdump_jit.bin NIP_VALUE ``` 5. Check if NIP is a valid address: - 0xC0xxxxxx = kernel code - 0xBFxxxxxx = PROM virtual address (prom_mem_phys_to_virt) - 0xFDxxxxxx = PCI I/O space (not executable) Report: exception type, faulting address, caller, what the code was trying to do.
