Hi,
I've got a dual-processor system built around the Intel SBT2 motherboard,
which uses the ServerWorks LE chipset. 2.4.3 SMP works fine. When I
build a UP kernel with IO-APIC support, I get this during boot:

2.4.3 has this behavior, 2.4.3-ac9 works fine. I found this in the -ac
changelog; perhaps it's relevant:
> 2.4.2-ac12
[...]
> o Remove serverworks handling. The BIOS is our (me)
> best (and right now only) hope for that chip
Here's the pertinent (I think) part of 2.4.3 .config:
CONFIG_MPENTIUMIII=y
CONFIG_X86_GOOD_APIC=y
# CONFIG_SMP is not set
CONFIG_X86_UP_IOAPIC=y
CONFIG_X86_IO_APIC=y
CONFIG_X86_LOCAL_APIC=y
Details available on request.
