Fatal problem, possibly related to AIC79xx

Fatal problem, possibly related to AIC79xx

[Antonin Kral]

Hi all,

I'm trying to install Linux (in particular Debian) to our new servers.
These servers are based od motherbard SuperMicro X5DL8-GG with aic7902
without RAID, 1GB RAM, one XEON 3.06GHz

I have two, really strange problems, first of all I have noticed, that
with enabled SMP support kernel detects TWO processors, but only one is
physically installed.

The second problem is, that I am not able to run almost any program.
E.g. if I try to execute free I'll get "Illegal instruction", for mount
I'll get "Segmentation Fault".

What I've tried:

  Vanilla kernels 2.4.25, 2.4.26, 2.6.6, 2.6.7. And almost all
combinations with/without:
          * SMP
          * APIC
          * Highmem
          * MTRR

All without ACPI and with aic79xx and e1000 build in kernel.

  I've tried Knoppix 3.4. The strange think was that I was unable to
load module for aic79xx, because of "no such device".

Does anyone have any idea how to solve my problems?

  Thank you, best regards,

        Antonin Kral

Looks like a hardware problem to me. Perhaps higher transfer rates obtained
with aic7xxx triggers it faster. You should really run cpuburn (burnBX) and
memtest86 on this box.

Willy

I've run memtest for more than 48 hours. And actually I have two boxes
with same behaviour. I was thinking about more precise check of SCSI bus
termination...

If you'd like to have just 1 processor instead of two, then
enter the BIOS SETUP and disable HyperThreading (HT),
or boot the SMP kernel with maxcpus=1.

I have no insight into your potential AIC79XX problem...
