SMP Problems with Gigabyte DA-686DX & PPro

SMP Problems with Gigabyte DA-686DX & PPro

Post by Christian Eber » Thu, 02 Oct 1997 04:00:00

We have a problem with our linux box, containing a Gigabyte DA-686DX
Mainboard and two PPro 200MHz. The system runs fine in single processor
mode, but is that dead slow when we are booting a SMP Kernel (e.g. 2.0.8
or 2.0.30). The boot messages are as follows:

<4>Intel MultiProcessor Specification v1.1
<4>    Virtual Wire compatibility mode.
<4>OEM ID: OEM00000 Product ID: PROD00000000 APIC at: 0xFEE00000
<4>Processor #0 Pentium(tm) Pro APIC version 17
<4>Processor #1 Pentium(tm) Pro APIC version 17
<4>I/O APIC #2 Version 17 at 0xFEC00000.
<4>Processors: 2
<4>Calibrating delay loop.. ok - 199.88 BogoMIPS
<4>Memory: 64108k/66496k available (736k kernel code, 384k reserved,
1268k data)
<4>This processor honours the WP bit even when in supervisor mode. Good.
<4>Booting processor 1 stack 00002000: Calibrating delay loop.. ok -
1.95 BogoMIPS
<4>Total of 2 processors activated (201.84 BogoMIPS).

Please note the BogoMips reported for the second processor...

Does anybody have any idea what's going on??

Thanks in advance.

1. Experiences with new Gigabyte 686DX MB?



   Has  anybody experiences with the  new Gigabyte dual PPro MB (GA-686DX)?
   Is it as good as the 586DX? Especially  is the BIOS  o.k., i.e. only NMI
   when unrecoverable ECC error, PCI config, etc.?

   Please send an e-mail!
