Root pointer (RSDP) not found

[ghost]

Hi Pike
I hope you're well. I have been trying to get Revoboot to work on my new z270 Kabylake rig but I keep getting a kp on very early boot:

Have tried switching ACPI patching off as I can boot without it but I still get the same error. It seems Revoboot cannot find the system RSDP even though in debug mode it says the address is 0x000f05b0. Do you think this is related to the new AppleACPIPlatform kext in HS rather than the boot loader as is is listed as one of the kexts involved further down the verbose output. Can't test on Sierra as I'm on the 'bleeding edge' and using betas as usual :)
Thanks
Dave
