Page about bisecting the kernel in the wiki?

Hi all,

I recently ran into an issue when upgrading my system, as I discussed in this post. Apparently it is related to the latest kernel (3.15.1), as downgrading to 3.14.6 resolved the problem. In that thread, I was encouraged to file a bug report upstream to the linux kernel. I have never filed a bug report before, and furthermore I never played with the kernel in any way. I have been browsing the bug reports and I see that often people are asked to bisect their kernel. There are a couple of blogs out there talking about it, and there's an entry in the gentoo wiki about bisecting the kernel, however it is quite scary for somebody with my experience to go on and try, because I couldn't find anything about bisecting in the arch wiki (yes, you can call me spoiled).

Is there any chance a page about bisecting the kernel will be introduced in the wiki? Should there be arch-specific instructions for something like this, or is it too generic?

These two pages seem like reasonable guides to bisecting:

http://git-scm.com/docs/git-bisect
http://git-scm.com/book/en/Git-Tools-Debugging-with-Git

Whether you need a special one for bisecting a kernel is questionable, since other stuff uses git as well.

I see.. I'm very very new to that (first time that I heard about bisecting, never submitted a bug report, not a programmer),
so I misunderstood the concept. I thought it only had to do with the kernel.

Thanks for the resources and the info.

EDIT: It's interesting though that Gentoo wiki has a dedicated page on kernel git-bisect.. The Debian wiki too.

We already have git guides in our wiki, maybe you can add the info about git-bisect to them https://wiki.archlinux.org/index.php/Git https://wiki.archlinux.org/index.php/Su … _Git_Guide or to https://wiki.archlinux.org/index.php/St … ging_Guide

Yes, if I end up doing the bisecting after all, I'll put adding to the wiki in my todo list. I'm still hoping I can avoid it
somehow though.. We'll see.

Agree. Please add how to bisect the kernel in the Archwiki, that would be very useful, of course including every little step, even those than could seems to be obvious.

Guys, I'm wondering what is it that you exactly do when searching for something on the wiki (if you try at all): both searching for "bisecting" in the ArchWiki search form, or even "ArchWiki bisecting" in Google, returns https://wiki.archlinux.org/index.php/Bisecting_bugs which is also categorized under https://wiki.archlinux.org/index.php/Ca … management and https://wiki.archlinux.org/index.php/Ca … rol_System ...

I'm not sure, but https://wiki.archlinux.org/index.php/Bisecting_bugs has been created in October https://wiki.archlinux.org/index.php?ti … did=342284 , while this thread is from June.

My apologies to Karol and the others, also to edoantonioco who is a new user and may not be experienced at searching in the wiki. At least, now this thread has a link to the correct article
As a penance, I've written a script that highlights old posts with bright red, so hopefully I won't make the same mistake until I get used to it and start ignoring it again...
