Hello,
I am having some trouble getting any smp kernel to run on my
ancient Pentium system. The problem I am having is that ( from what I have
read in various linux smp documents) the my old Intel motherboard mp table is
lying about the IRQ for the Real Time Clock. Thus preventing me from
booting. The system boots up and detects both processors and then right
after the IO-APIC starts I get this:
IO APIC pin 2, 13 not connected.
.. MP-BIOS bug: 8254 timer not connected to
IO-APIC
...trying to set up timer as ExtINT... failed
...tryng to set up timer as BP IRQ... failed
Kernel panic: IO APIC + timer doesn't work!
In swapper task - not syncing
I have read through the code and see that the error is coming
directly from the IO-APIC code. I am assuming that you need the IO-APIC
for SMP to work. Am I wrong? the todo list for the smp.c file states
one of the todos is to separate IO-APIC from SMP. If I am wrong is it
possible to prevent me from using IO-APIC. I am not to keen on SMP
systems. This is my first attempt at it.
Any help/comments would be appreciated.
The system specs are like this:
Intel Xpress Server 1.19.AM0 Bios
dual Pentium 66 stepping 5 ( yes I know stepping
5 cpus have lockup problems but his isn't really a lockup... I can't even bootup
far enough to see the cpus lockup)
2 - 8meg simms on the motherboard
6 - 8meg simms on the memory expansion card
ISA ne2000 nic (detects on AutoProbe.. kinda sweet for 8 bucks
:))
EISA 2 DPT pm2122 Raid controllers (with 4megs of RAM and
array module)
EISA 1 DPT pm2122 SCSI card ( no ram, no array
module)
EISA AIC7170 (disabled)
all Seagate scsi drives ( 3 - 2gigs, 2 - 1gigs )
Exabyte tape drive (SCSI)
NEC 4x CD (SCSI)
standard floppies ( 1.44, 1.2 )
plz don't tell me I have to put NT back on this
machine!! seems such a waste of hardware.
