dual opteron problems, tyan 2870 board

[Corin Langosch]

Hi all,

i just bought a new 2x244 opteron,tyan tiger k8s 2870,
4gb registered ecc ram system. no addional cards
inserted, only one IDE and one SATA device.

i tried to run the setup with the original debian
kernel 2.6.6-1-k7-smp, but the system hangs right
after the line "initrd-tools: 0.1.69".

so i downloaded the sources for 2.6.6 and compiled
them myself, optimized for dual opteron. unluckily
exactly the same happens.

when i enable the apic 2.0 support in the bios, the
system hangs even ealier right after the first
"calibrating delay loop...".

when i boot the system with the "nosmp" and apic 2.0
disabled (normal apic still enabled) the system
hangs somewhere after "hda: max request size...".

the only way to get the system running is to fully
disable the apic support in the bios and run the
system with "nosmp". :-(((

additional info:
when i boot using the 2.4.26-k7-smp kernel, the system also
hangs. sometimes when saying "loading data into ramdisk.."
and sometimes later. one time a "decompression error..."
was displayed. when i boot using "nosmp", the system
boots fine. with the 2.4.26 kernel, i dont need to disable
APIC completely.

i hope that anyone could help me,
corin

Sounds like hardware problems on your board. It is unlikely that
any kernel can fix them.

e.g. run memtest86 over night to check the memory and probably
something is wrong with your second CPU too.

I would talk to whoever sold you the kit.
