Bug 99308 – module-init-tools-3.2_pre7-r1 autogenerates incorrect modprobe.conf

• Status: RESOLVED FIXED
• Product: Gentoo Linux

[Description Paul Mickus 2005-07-17 03:51:12 UTC]

As of module-init-tools-3.2_pre7-r1 modules-update generates a
/etc/modprobe.conf with incorrect aliases. For example "alias intel-agp agpgart"
is an incorrect alias. The modules agpgart and intel-agp are two different
modules. What happens is intel-agp is aliased to agpgart, thus loading it twice
in my /etc/modules.autoload.d/kernel-2.6. This causes problems in X.org since
without intel-agp being loaded I have no /dev/agpgart and therefore no DRI
(without AGP DRI is disabled by default).

Reproducible: Always
Steps to Reproduce:
1.boot system
2.modules-update is run in init and generates incorrect modprobe.conf
3a.the next init step is to load the modules in
/etc/modules.autoload.d/kernel-version
4a.incorrect alias may lead to an important module not being loaded

3b. modprobe modulename
4b. if modulename has incorrect alias, it will not be loaded 

Actual Results:  
incorrect loading of modules

Expected Results:  
correct loading of modules

does 3.2_pre7 work ?

It did at one time but now unmerging 3.2_pre7-r1 and merging 3.2_pre7 makes no
difference.

[Comment 3 SpanKY 2005-07-17 04:29:02 UTC]

try downgrading baselayout to 1.11.12-r4

[Comment 4 SpanKY 2005-07-17 04:30:07 UTC]

err actually scratch that

this is because of the updated alias patch i added for module-utils from debian

see files/modutils-2.4.27-alias.patch

i can just rip out the agpgart chunk that is causing you problems

Yeah I see the part that is causing problems. I suggest that if the kernel
version is 2.6 that this patch not be applied. Since 2.4 has a different module
architecture.

I am going to assume this will need punting as well:

Hmm, maybe not, forget I mentioned it.

[Comment 8 Martin Schlemmer (RETIRED) 2005-07-17 07:14:33 UTC]

I think we can punt that hunk entirely, as we provide different configs for
2.4/2.6 kernels.

[Comment 9 SpanKY 2005-07-17 07:29:08 UTC]

punted the agpgart hunk from the patch

az: which hunk are you talking about ?

[Comment 10 Martin Schlemmer (RETIRED) 2005-07-17 07:40:24 UTC]

The one you punted :)  Guess this is fixed.

[Comment 11 Paul Mickus 2005-07-17 08:48:58 UTC]

I can confirm after remerging module-init-tools that this bug has been fixed.
Thanks alot guys.
