Subject: ram and swap faults, help me!
Date: Sun, 26 Sep 1993 05:36:23 GMT

Memory and Swap errors:

Here is specific data concerning my problems:

After using swapoff and and then makeswap, in order to reformat the swap
drive -- hoping it would solve my problems -- I got this:

GENERAL PROTECTION: 0000
EIP: 0010:0011B619
EFLAGS: 00010206
EAX 882527E2 EBX 00006493 ECX 013F480 EDX 00003EBC
ESI 00000000 EDI 00000000 EBP 00000342

DS 0018 ES 0018 FS 002B GS 002B
PID 59 PROCESS NR: 14
66 39 68 0C 06 85 90 00 00 00

TRYING TO FREE KERNEL PAGE-DIRECTORY: NOT GOOD.
SEGMENTATION FAULT.

        Well, thats the message. I have had several other errors
pertaining to ram and swap space. Such as "NMI received. Dazed and
confused, but rying to continue.", "unable to handle paging request at
address c0000012", "trying to free non existant swap page" , "bad page
table [00cf902c] =00000400", and "memory fault."

My system configuration is as follows:

486 dx2/66.
20 mb of ram.
AMI bios
wd 1003 MFM and floppy ctrlr @ primary address
two mfm drives. The second mfm is an xt2190 maxtor with over 1024 cyls.
This is the drive with linux.
Ultrasor 34f vlb scsi-2 ctrlr. Mbox I/O @340H Bios segment
@cc000-cffff. IRQ 15.
Runs a Maxtor 340 mb SCSI-2 drive.
ALL shadow is OFF.
LILO is not installed.
ATI VGA Wonder 512k video card.
PAS 16 Audio card
The rest is likely not significant.

I am running the Slackware pl13 release of Linux.

I get the bugs while running stuff, mostly when I put stuff in the
background. If I leave the system idle, i get the errors, and the VC
locks up, but others are temporarily ok.

Please help. Thanks!
