Thanks for your quick response. I hope I am replying via this email
through the correct channel. The original inquiry (ticket 1272) is
copied to the bottom of this email. The output from ksymoops is
reproduced directly below (C). This also shows the loaded modules (A)
and the modproble command which generated the oops (B)
Hope this is helpful information.

-o /lib/modules/2.4.20/ (default)

Warning: You did not tell me where to find symbol information. I will
assume that the log matches the kernel and modules that are running
right now and I'll use the default options above for symbol resolution.
If the current kernel and/or modules do not match the log, you can get
more accurate output by telling me the kernel version and where to find
map, modules, ksyms etc. ksymoops -h explains the options.

[Original inquiry]
Ticket #: 1272 Timestamp: 2003-06-14 13:18:02-07 Version/Environment: lm_sensors 2.7.0 Linux 2.4.20 SMP
Subject: i2c-amd756 segfault with kernel 2.4.20 Category: kernel
Contact: r.young at irl.cri.nz Client Machine: ippool31-186-irl.remote.irl.cri.nz Status: Examined/Unsolved
Problem in detail:
Hello, I am trying to use i2c/lm_sensors v.2.7.0 under Linux v.2.4.20
but the i2c-amd756 module segfaults when loaded (with modprobe or insmod).
I give the complete error message below. I have a Tyan MPX 2466B m/b.
and use gcc 3.3.2 (with the Slackware 9.0 distribution).
I am using the "stand-alone" option (method 1). Therefore I didn?t
apply any of the patches as they seemed to relate only to the kernel
option. There was an initial compile problem but that was fixed according to
a suggestion made in ticket #1189. There were no further problems.
modules.conf and sensors.conf were configured as suggested by
Tyan on their website.
My impression is that this is related to the current kernel version
(2.4.20) since I have not had this problem in the past. After a search
I looked at some other tickets (#1235, 1096) but they did not seem to
relate directly to my problem.
Thanks for any help with this.
Regards,
Roger Young.
