IO-APIC in SMP dual Athlon XP1800

IO-APIC in SMP dual Athlon XP1800

[Scorpion]

Hi follows,
I'm getting in troubles with a A7M266-D motherboard with two
Athlon XP 1800 cpus (yes, XP not MP!).
Following the screen shot of my problem:
^-------cut here---------^

2-23 not connected.
..TIMER: vector=0x31 pin1=2 pin2=0
^-----cut here-----^

After spend some times put printk's in kernel source like "Reach this point!"
I was trying disable IO_APIC in .config file but some link erros ocurred. 
Has any way to turn IO_APIC disable? Or its extreme necessary?

Thanks,
Ricardo.

I tried using:

2.4.18-3smp (red hat 7.3) with options: hdc=ide-scsi
and using ext3 fs.

2.4.18-5custom (red hat 7.3 recompiled with smp, bigmem and ext3 fs) with 
options: hdc=ide-scsi

2.4.18-5smp (red hat 7.3 upgrade of bigmem header problem and ext3 fs problem) 
with options: hdc=ide-scsi

2.4.18-3 (red hat 7.3 uniprocessor for get up) with options:
hdc=ide-scsi noprobe mem=256m

details about the last:  
    When changing mem parameter value to 64 or 512 or 128 its stop in 
different places (using the "printk debbug technic") in io_apic.c/apic.c 
parts.

After that I tried the kernel from kernel.org and got the following message:

-----------^^^cut here^^^------------

Its a error? Should a try the last last kernel patchs?

I'm not thinking about a hadware problem, cause BIOS detect
2 CPUS and Linux agree with this. Am I wrong?

Ricardo.

Hi All,
I got my Dual Athlon XP1800 working now. 
Everything gonna well after changed MP 1.4 Support to disable in BIOS, and 
leaving MP table enabled.
Anyone knows if linux 2.4.19 has not yet a full implemantation of MP 1.4 or if 
it is just a BIOSes bug?

Thanks in advance,
Scorpion.

On the 1004 BIOS with the ASUS it seems to be a bios table error. Later
BIOSes fixed it, then removed the option, then broke lots of other
stuff. I went back to 1004 so I dont know how the newest fare

I am using 1006.  I have enabled MP 1.4 in order to get the IRQ
numbers 16 and beyond.  I am not sure how useful that is since several
PCI IRQs are shared and there are lots of free ones.  Anyhow, MP 1.1
works just fine too.  I am using the Athlon MP 1900+ CPUs.

Note to anyone who is considering this cpu/motherboard, this combo
uses *shedloads* of power.  400W is *not* enough (I've seen Alan post
to this effect before but it bears repeating).  Also, make sure you
have good case airflow -- all that power that is being consumed is
being turned into heat.  Aftermarket CPU heatsink and fan are a good
idea.  Unfortunately, it is a bit crowded for 80mm CPU fans though.

Things are stable now once I mitigated the heat death problem.

Well I'll probably tell you what just about everyone else here will.
If you use XP procs on a MP system you are on your own.  If you
lucky they will work, if you aren't they won't.  It appears that you
are not lucky.
