more detailed information about the AMD 1.6+ GHz MP smp-problem with latest kernel

[mw]

Dear list members,

As I've posted a message before not including detailed information about the system, I'm now
posting with very detailed information looking for help to get everythign fixed ;-)

Motherboard: ASUS A7M266-D, AMD-760MPX
CPU: AMD Athlon 1600+ 266 FSB
RAM: DDRAM, 512 MB, PC266 ECC registered


The system is a RedHat 7.2 linux installation ... I've first attempted with the included SMP-kernel
which didn't work. Then updated the system with the latest RedHat-build kernel ... rebooted,
SMP-kernel still didn't work. So I saw the last chance in building my own kernel, included some
multi-cpu stuff. The system hang after detecting the 2nd CPU ...

Anybody can provide help to make the 2 CPU's work? ;-)


Cu,
mw

ive got the same motherboard with the same results.

2.4.18-rc2 and 2.4.18-rc2-ac1 would not boot

redhat's latest 2.4.9 version would only boot with noapic passed to the
kernel and the bios had mps 1.4 spec on and mp table disabled. but
sometimes that paniced and would not boot.

if anyone knows what bios settings and kernel bits make this board
stable please pass that info along...

thanks

rob.

MP table on 
MP table version 1.1

You want 2.4.18-rc2 in order to get the fixups for what appears to be a BIOS
PCI compliance config problem. You also may need to remove any 3com gige
cards using broadcom chipsets.

ah thank you, those settings work nicely.  turns out i had a bad
motherboard.  the new one seems rock solid (after one day).  redhat 7.2
kernels 2.4.7-10 and 2.4.9-21 worked for me, as does 2.4.18-rc4.  

so if anyone else is having trouble with an asus a7m266d *with the
proper bios settings*, its possible (likely?) you've got a bad
motherboard.

ps- for the record my stable configuration includes 2 AMD Athlon(TM) XP
1900+, matrox g200, intel eepro100, hdd, and floppy.
