Subjectpaging Oops in 2.4.1{4,5-pre1}
From
Date

I have a problem with kernels 2.4.14 and 2.4.15-pre1. As soon as my
system needs to page, it generates the following Oops. I can
duplicate this error at will by running a few memory-intensive
processes, such as 4-5 simultaneously compiles, StarOffice, and
Netscape. If I duplicate the test, but running with no swap, just
RAM, then I get the expected "Out of Memory: Killed process..."
errors.

The system is an IBM xSeries 200 with 128MB, Celeron 667Mhz, and 3Ware
Escalade 6400. All fixed disk access is via the Escalade, even swap.
Additionally, there is a CDROM, CD-RW, and Travan tape drive connected
to the motherboard IDE controllers. The system runs very reliably
with kernel 2.2.16-22 as delivered with RedHat Linux 7.0, with the
addition of the 3Ware driver. (With the new kernel, I'm running the
3Ware driver that came with the kernel.)

I tried to look up the EIP: values, ie. 00000500 & c10c0a47, in the
namelist using nm(1), but I don't have confidence that they're
meaningful, since c10c0a47 isn't in the range of addresses output by
nm.

The kernel was built using:
% gcc --version
2.96
% ld -v
GNU ld version 2.10.90 (with BFD 2.10.0.18)
% as -v
GNU assembler version 2.10.90 (i386-redhat-linux) using BFD version 2.10.0.18

Please let me know if there is anything you'd like me to try in order
to gather more information.

Dan.
