So the problem here is that the BIOS completely screws us over. It wrecks the ACPI-ID table with that option to limit the number of CPUs exposed to the OS (note that it didn't need to do that, it could have enumerated them as empty, instead of not there at all) while keeping the CPUID of the CPUs as reporting they have many (12? was it) cores. This results in inconsistent state, and we're left with nothing useful. > fix the uncore code to initialize pmu boxes on cpu hotplug as well Can't.. it uses the boxes at STARTING time, and we can't do allocs there. Not can we alloc earlier, because we don't know max_packages is going to increase.
