AMD 5x86-P75 S (133 MHz) and seg faults

Post by Eva Bre » Fri, 06 Sep 1996 04:00:00



Greetings -
  I have been trying for several weeks to install linux on a shiny
new machine running on an AMD 5x86-133 processor, unfortunately,
the machine dies, often during boot, sometimes on exiting fdisk, and
if not then, then after rebooting when I try to run mke2fs... I have
been using a modified version of the Slackware distribution, with
a 2.0.0 kernel.  I have even tried to change motherboards (someone
indicated to me that this might be the problem...), but to no avail.
Currently, the motherboard is a Soyo SY-4SAW2 with an SiS 85C496
chipset.  Common errors have are:
 Segmentation fault, unable to handle kernel paging request at
virtual addres (x), idle task may not sleep (about five times),
and several others.  Any ideas would be greatly appreciated...

   Thanks in advance,

Are you using any Bus Mastering cards?

Using one for the past year almost, with absolutely *NO* problems
 at all - with 36M of RAM, it runs like a charm :)  It sounds like
 you might have a problem with one/all of your memory SIMMs. There's
 nothing wrong with the MB as far as my experience goes. The fact,
 however, is that you may have encountered two faulty MB's - I know
 it sounds kinda "improbable" but friends' "MB horror-stories" tell
 otherwise...

1. AMD 5x86/133 then parity errors

Hi,

After upgrading my 486DX2/66 to an AMD 5x86/133 and voltage regulator I
experience parity errors whenever I put something in memory bank 2.
I have 32 MB as 8 times 4 MB, five are 80ns 3 are 70 ns.
They work fine with the 486DX2/66.
Now with the AMD whenever I put only 16 MB in the lower memory bank in
whatever mixture of chips, this works fine.
But as soon as I put whatever mixture in the second bank I get parity
errors.
Sometimes immediately when booting , sometimes minutes to hours later.

Has anybody a clue what could cause this.
I think defective chips should also cause an error when they are in the
lower 16 MB.
Or are the first and second memorybanks treated differently.

BTW this happens with LINUX and WIN95

Otherwise the AMD 5x86/133 works allright.
