Intel XNU bug report



Now that the source is released, we might as well get to work.
That's the point of releasing the source in the first place, right?

File: xnu-792.10.96/osfmk/i386/acpi.c
Line: 151

if (cpu_mode_is64bit()) {
cpu_IA32e_enable(current_cpu_datap());
cpu_desc_load64(current_cpu_datap());
kprintf("acpi_sleep_kernel 64-bit mode re-enabled\n");
fast_syscall_init64();
} else {
fast_syscall_init()
}

Bug: The 64 bit mode should be restored if the cpu is *NOT* currently in 64 bit mode.

The first line should read:
if (!cpu_mode_is64bit()) {

Somebody please file a RADAR for this, as I'm having problems filing the report.
Thanks,
Ernesto.
