Bug 36243 – gentoo-sources-2.4.22-r2 i2c and lm-sensors version mismatch

• Status: RESOLVED FIXED
• Product: Gentoo Linux

[Description Daniel Westermann-Clark 2003-12-21 09:36:56 UTC]

Using gentoo-sources-2.4.22-r2 causes a version mismatch with i2c and lm-sensors when using the x86 branch.  The gentoo-sources-2.4.22-r2 package appears to include i2c version 2.8.1 (based on what patches.txt says), while lm-sensors is still at version 2.7.0.  As a result, lm-sensors does not work for me when running 2.4.22-gentoo-r2 - it either segfaults or hangs.

Reproducible: Always
Steps to Reproduce:
1. emerge sync
2. emerge -u gentoo-sources
3. Reboot
4. emerge -u sys-apps/lm-sensors (which requires sys-apps/i2c-2.7.0)
5. Reboot
6. sensors

Actual Results:  
The sensors binary either segfaults or hangs.

Expected Results:  
The configured sensor readings should have been printed.

gentoo-sources-2.4.22 has lm_sensors inside the kernel, so you don't need to emerge it seperately.

[Comment 2 Daniel Westermann-Clark 2003-12-21 10:09:05 UTC]

If I'm not to emerge lm-sensors, where should I get the userspace tools?

[Comment 3 Daniel Westermann-Clark 2003-12-24 22:33:42 UTC]

I fail to understand how this is not an issue.  I understand that gentoo-sources-2.4.22-r2 includes i2c-2.8.1 and the _kernel drivers_ for lm-sensors-2.8.1.

However, if I want the userspace lm-sensors tools (e.g. sensors), I will need to emerge sys-apps/lm-sensors.  In the stable branch, the current version of this package is 2.7.0-r1, which has the following dependencies:

DEPEND="~sys-apps/i2c-2.7.0"

This obviously leads to problems with some of the lm-sensors modules not being the right version, which explains the segfaults I experienced after installing this package.

Again - I don't see any way to get the lm-sensors userspace tools from gentoo-sources-2.4.22-r2.  If I try to get them by installing sys-apps/lm-sensors, bad things happen.  Judging by the addition of CCs to this bug, others are having this problem.  I'm going to repoen it pending further clarification.

Fixed - lm-sensors-2.8.1 is now stable on 'x86' and will also accept gentoo-sources-2.4.22 as a dependency instead of i2c-2.8.1.

[Comment 5 Daniel Westermann-Clark 2004-01-04 09:59:32 UTC]

Unless I'm missing something, lm-sensors is still uninstallable with gentoo-sources-2.4.22-r2.  It's still marked ~x86:

http://www.gentoo.org/cgi-bin/viewcvs.cgi/sys-apps/lm-sensors/lm-sensors-2.8.1.ebuild?rev=HEAD&content-type=text/vnd.viewcvs-markup

Additionally, both i2c and lm-sensors appear in /usr/portage/profiles/package.mask:

# John Mylchreest <[e-mail]> (14 August 2003)
# Headers have changed and break support with many video drivers such as
# bttv or zoran. Kernel patch is being worked on bt lm_sensor people afaik
>=sys-apps/lm-sensors-2.8
>=sys-apps/i2c-2.8

[Comment 6 Tim Yamin (RETIRED) 2004-01-04 10:35:46 UTC]

Fixed - lm-sensors-2.8.1 is now stabilized on 'x86' and I've updated packages.mask from 2.8 to 2.8.2.
