| |
On my Intel imac, /sys/firmware/efi/systab is the following:
ACPI20=0x1fefd014 ACPI=0x1fefd000 SMBIOS=0x9fec9000
if I have a kernel with a 2:2 user/kernel split, and
SMBIOS=0x5fec9000
if I have a kernel with a 3:1 split. The correct value is 0x1fec9000, which is what the kernel prints at boot time. The following trivial patch seems to fix things.
