I have a box which runs 11.1 fine & seemingly 2.6.27.X kernels, but not 11.2 or any 2.6.31.X kernels I've tried.

Are there any archives of "golden" kernels, so I could do a bisect to find which release breaks things?

No, I don't think we keep old Factory packages anywhere, sorry.

Thanks for answering so quick! No I can't find anything useful on a mirror, in old SuSE 8.x days, there'd be multiple kernel versions lying around in part of the update tree alongside things like XFree & KDE supplementaries. Perhaps a generic kernel thought to be "solid" could be saved from "kotd", so someone with last release reporting a bug could narrow things down and "do something useful" without it costing too much disk space.

I found one x86 .29-pae from last Feb: http://fm.no-ip.com/tmp/SUSE/Factory/

Thanks, I got one from RPM Search http://rpm.pbone.net/index.php3/stat/4/idpl/12133175/com/kernel-default-2.6.... which I've downloaded, which some guys on forum have found and used.

I am trying that after all, the git one I found had fan blowing like mad, and didn't boot, I'm can't be sure if it's a 2.6.29 "feature" or just due to the RC4 + git. Basically if that one had worked, it would mean I could go to 2.6.30 with confidence, it failing means I am would have to try 2.6.29 again.

For sleuthing purposes, the later version ones are better, perhaps I could give a kernel from another distro a go, which released in April and still support it.

Mandriva 2009.1 in April used 2.6.29.1. Fedora 11 in May used 2.6.29.3. -- The husband should fulfill his marital duty to his wife, and likewise the wife to her husband. 1 Corinthians 7:3 NIV Team OS/2 ** Reg.

Using generic binary rpm's would be a huge time saver on compiling vanilla from source.

We don't have a git repo of expanded trees yet,

Honestly for what I'm doing, an archive of the 'best' 2.6.28, 2.6.29 & 2.6.30 rpm's would let me figure out which release introduced the issue. There's not just me with a box, that fails to boot 11.2 so some sort of fallback kernel (to run installer in degraded mode) wiith hopefully a small net archive of unsupported binaries, would help generate better kernel bug reports. Last time I got involved with kernel debug testing, I had to set aside about 20 GB of disk space, even after I de-bloated the kernel config, and it took about 2 1/2 hours to compile on a dual Athlon MP box. Hopefully you'll understand why the thought of doing a git bisect over a year of source changes, is pretty daunting. :) Rob -- To unsubscribe, e-mail: opensuse-kernel+unsubscribe@opensuse.org For additional commands, e-mail: opensuse-kernel+help@opensuse.org

That's not a "de-bloated" kernel config :)

No, symbolic debugging info was on. I got a patch from Alan Cox to try against an -ac kernel, and he had debug stuff enabled and at first a very general config. I did slim things down after fair amount of trial and error getting new options wrong and re-builds. It was a lot quicker with 2.2, or early 2.4, when I stopped bothering re-compiling the kernel because you guys got the generic almost as fast and I had a decent amount of memory for the times (512MiB).

Use the 'make localmodconfig' option in the latest kernel version to provide you with a config that is tuned for your machine.  It only selects the options that you have loaded modules for and makes for a _much_ faster build.

I hope so, thanks :) I'm giving Fedora 11 a quick spin, then will give the Kernel Git stuff a shot next week. -- To unsubscribe, e-mail: opensuse-kernel+unsubscribe@opensuse.org For additional commands, e-mail: opensuse-kernel+help@opensuse.org

I have the last 2.6.29 and 2.6.30 SUSE kernels in my OBS repos for such a purpose:   home:tiwai:kernel:2.6.29   home:tiwai:kernel:2.6.30

These are no copy of old packages but the rebuilt ones by BS.  So, the binaries are different.  But, it's good for bisecting.

2.6.28 doesn't exist as a SUSE kernel here.  We sticked with 2.6.27 for a long time and switched almost directly to 2.6.29-rc, IIRC.

You are a star! Unfortunately 2.6.28 is my next target, as I've reproduced the same hang after PCI bus scan with Fedora 11, that I've seen with 2.6.31. I shall presume no objections to posting about these kernels on the openSUSE forum, as there's been a few ppl in the market for "legacy" kernels, and it'd encourage better bug reports.

Knoppix 6.0.1 has 2.6.28.4.

Another no go! That was quick to try out :) Looks like my best bet is to try and bisect between a vanila 2.6.27 and 2.6.28 I'll use OS 11.1 as I have better boxes to do kernel builds on than the target. Plan to run Greg's kernel config suggestion there, and then transfer the file.
