looks like a defective $PIR table.

I added the following to kernel spec file. It
works for me. BTW, Windows XP has no problem.
----
%ifarch %{all_x86}
# Needed for SATA drives on Intel D875PBZ motherboard.
for a in i386-BOOT i686; do
  cat >> configs/kernel-%{kversion}-$a.config <<EOF
CONFIG_X86_UP_APIC=y
CONFIG_X86_UP_IOAPIC=y
CONFIG_X86_LOCAL_APIC=y
CONFIG_X86_IO_APIC=y
EOF
done
%endif

yup this proves the $PIR table is defective; UPAPIC makes the kernel use the
mptable not the $PIR table for interrupts.
Unfortionatly we can't enable this by default since it breaks far more than it
ever fixes.

Closing this as "NOTABUG" since it's a bios bug, and thus not a kernel bug.
