Subject: [linguist-linux@rich-paul.net: 2.4.14 oops: cdrecord, ide-scsi]
Date: Mon, 7 Jan 2002 08:17:40 -0500 [thread overview]
Message-ID: <20020107081740.C7156@monster.rich-paul.net> (raw)
This file is availiable at: http://www.rich-paul.net/oops,
ksymoops output at end, /--ksymoops--/
I have a repeatable oops when using cdrecord with my TEAC ide
cd-writer and ide-scsi. It happens at the beginning of writing a
cdrom, and causes a hard freeze of the system, from which nothing
except the kiss of a prince or a touch of the reset button will wake
it. Being no prince, I choose the later.
I'm a coder, and willing to help as much as I can in tracking this
down, but my job limits my time. I know nothing of the kernel, except
that it is subtle and quick to anger.
The oops seems very similar to one that was reported on the list
against 2.5.something, but I have not yet tried against that kernel,
with or without the prescribed patches. I will, but I suspect we
should fix the stable tree as well. The code has changed alot between
the two versions, and I could not backport the patches. Somebody who
knew their way around the kernel probably could.
The simplest way to repeat the problem seems to be:
using a kernel with a Serial console, boot with init=/bin/bash
execute the following commands:
|# Mount filesystems
|mount /proc
|mount /dev/fs
|mount -oro /archive
|mount -oro /usr
|mount -oro /opt
|mount -oro /boot
|
|# Set up shell
|HOME=/root exec bash --login
|
|# Load modules
|insmod ide-mod
|insmod ide-probe-mod
|modprobe ide-scsi
|
|# Prepare for oops report
|rm -fr /oops
|mkdir /oops
|cp /proc/ksyms /oops
|cp /proc/modules /oops
|cp -ar /lib/modules/2.4.14/ /oops/kdir
|cp /boot/2.4.14/System.map /oops
|cp /boot/2.4.14/config /oops
|
|# avoid viewing e2fsch yet again
|mount -oremount,ro /
|
|# do the dirty deed
|cdrecord -dev2,0,0 /archive/masterlink.iso -v
Here are files that may be relevant to tracking this down:
1. [1]Oops report, interpreted by ksymoops
2. [2]Shell script to execute commands above
3. [3]All console output produced, from boot to freeze
4. [4]Configuration of my kernel
5. [5]cat /proc/pci
6. [6]The part of the cap that was fed to ksymoops
7. [7]cat /proc/modules
8. [8]System.map
9. [9]My modules directory, in all it's glory
10. [10]My kernel as it was that fateful day
Other observations:
1. The oops occurs in (at least) kernels 2.2.19 2.4.5 2.4.14 2.4.17
2. There was a config at one time under which I could burn cds
without burning the system. This config is lost in the mists of
time, and try as I might, I cannot find on that works now.
3. I have tried turning off dma with hdparm to no avail, but am not
even sure if hdparm will have any effect on a device that is an
IDE claiming to be a SCSI. Is there something I should try along
these lines? Of course, it doesn't fix the oops, but it would get
me burnin'.
4. I have tried removing all other IDE devices from my system,
compiling with and without the various ide modules, etc, etc. No
joy.
5. If I run cdrecord on a normally running system, rather than a
clean boot, the oops usually shows itself as being from dnetc.
