You run an incorrect setup and need to review and fix it. For instance:
renaming of _OSI method to XOSI but no SSDT-XOSI table. They go together!
totally incorrect iGPU property injection for the Haswell cursor memory size (invalid key, invalid type!); that's the most likely reason you experience those crashes...
duplicate and inappropriate properties injection in your patched DSDT for your iGPU (other devices not checked); that's also likely to contribute to the crashes...
