The problem I have is that some mainboards, like my i850 ASUS P4T-E, have I/O-APICs but no MP tables. The only way for the Linux kernel to discover the I/O-APICs on these mainboard is through MADT parsing. However, this currently requires me to enable all of ACPI, which I don't need or want for many reasons, including code bloat and behavioural side-effects. Replacing "HT_ONLY" with "MADT_PARSING_ONLY" would be ideal, IMO. /Mikael
