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.

2.6.29 2.6.30 || 2.6.28

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

I can't see any alternative though. Good luck! -- Jean Delvare Suse L3 -- To unsubscribe, e-mail: opensuse-kernel+unsubscribe@opensuse.org For additional commands, e-mail: opensuse-kernel+help@opensuse.org

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. -- To unsubscribe, e-mail: opensuse-kernel+unsubscribe@opensuse.org For additional commands, e-mail: opensuse-kernel+help@opensuse.org

We don't keep development binary images around that long. You don't need to bisect through the vanilla kernel, though. Now that the kernel git repo is public, you can do it directly with the patches. We don't have a git repo of expanded trees yet, though we're still discussing it. -Jeff -- Jeff Mahoney SUSE Labs -- To unsubscribe, e-mail: opensuse-kernel+unsubscribe@opensuse.org For additional commands, e-mail: opensuse-kernel+help@opensuse.org

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.

That's not a "de-bloated" kernel config :) 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. hope this helps, greg k-h -- 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.

Knoppix 6.0.1 has 2.6.28.4. -- 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.

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.

If you have multiple machines, you may want to consider using the 'icecream' package to distribute build load. All the configuration that is needed is starting up the daemons on all your nodes (designating one as the scheduler), setting up the environment on the node on which you'll type make[1], and ensuring that /opt/icecream/bin is before /usr/bin in your path. I have 11 cores spread across 4 machines and regularly do 'make -j16' for builds. -Jeff [1] /usr/lib{,64}/icecc/icecc-create-env /usr/bin/gcc /usr/bin/g++ and then set the ICECC_VERSION environment variable to the file it outputs. You can move or rename it so long as ICECC_VERSION points to it. You'll know if you get it wrong since it'll complain about ICECC_VERSION not pointing to a valid archive. -- Jeff Mahoney SUSE Labs -- To unsubscribe, e-mail: opensuse-kernel+unsubscribe@opensuse.org For additional commands, e-mail: opensuse-kernel+help@opensuse.org
