Private
>Environment:
i386 (ASUS P5N-E Motherboard)
>Description:
The kernel is unable to find any SATA or IDE devices with apic enabled (which is required for Intel Core 2 CPU...). The following messages appear with verbose logging (hand copied):
ata0: stat0=0x80 err=0x80 lsb=0x80 msb=0x80
ata0: stat0=0x80 err=0x80 lsb=0x80 msb=0x80
ata0: stat0=0x80 err=0x80 lsb=0x80 msb=0x80

hptrr: no controller detected
An amd64 base and kernel will be checked to see if this problem also exists using amd64.
>How-To-Repeat:
Boot system with SMP enabled (and apic) on ASUS P5* Motherboards
>Fix:
It has been hinted that there is a IRQ conflict between ata0 and apic.
It is also possible that RELENG_6_* worked (unverified)...
WORK AROUND: disable apic with:
set hint.apic.0.disabled=1 # in boot loader...
