He said that CONFIG_X86_UP_IOAPIC=y means that if
IO-APIC _is_ present on the motherboard then it will be used.
But i pointed out that acording to intel's
i850MV board specification update:
ftp://download.intel.com/design/motherbd/mv/A7258705.pdf (8-9 page)
this motherboard supports 16 irq in PIC mode and 24 in APIC mode.
So it seems to me that the problem is with kernel-bios communication.
Maybe the kernel needs the bios to supply the SMP layout?
Or ther is need to relocate the DMI scan to early boot stage?
I supply my DMI decode output:
SMBIOS 2.3 present.
DMI 2.3 present.
