[opensuse-kernel] Interrupts from the i915 module
by Volker Krueger 30 Jan '09

30 Jan '09

Hi, in the 2.6.27.13-9 kernel, the i915 still generates a lot of interrupts which eventually costs on a laptop valuable energy (up to 20% difference on my laptop at least) I heard in the thinpad forum that this is actually a bug and that it is fixed in 2.6.28. However, it seems that in Ubuntu, the fix was propagated as a patch into 2.6.27 (intrepid-proposed, 2.6.27-11-generic x86_64?) Is there any plan to propagate that change into the 2.6.27 suse kernel as well? best, Volker -- To unsubscribe, e-mail: opensuse-kernel+unsubscribe(a)opensuse.org For additional commands, e-mail: opensuse-kernel+help(a)opensuse.org

[opensuse-kernel] Disk space requirement of KOTD build from source
by Markus Koßmann 29 Jan '09

29 Jan '09

Today I run out if diskpscae when building a KOTD with "default" configuration from sources. I found that the build now nees 3.5G disk space. the same build of 2.6.27.7-9 only needs 888M. The installation also need much more spae than before : rw-r--r-- 1 root root 2511648 29. Jan 04:35 vmlinuz-2.6.27.13- HEAD_20090128193548_5c4d0ded-default -rw-r--r-- 1 root root 2576096 5. Dez 03:52 vmlinuz-2.6.27.7-9-default and the modules and in /lib/modules: 84M 2.6.27.7-9-default 893M 2.6.27.13-HEAD_20090128193548_5c4d0ded-default Is that change intended ? -- To unsubscribe, e-mail: opensuse-kernel+unsubscribe(a)opensuse.org For additional commands, e-mail: opensuse-kernel+help(a)opensuse.org

[opensuse-kernel] bug in kernel-source-2.6.27.13-2.1 from http://download.opensuse.org/repositories/Kernel:/HEAD/openSUSE_Factory/
by Rainer Klier 28 Jan '09

28 Jan '09

hi list, i think, there is a bug in the latest factory-kernel 2.6.27.13-2 from http://download.opensuse.org/repositories/Kernel:/HEAD/openSUSE_Factory/. at least the kernel source has a bug, i think. i tried to install latest nvidia-driver 180.22 on an opensuse11.1 x86_64 system. former kernel 2.6.27.12-1 had no problems with this. but this time, it was not possible to load nvidia kernel module. the installation-script stopped, and told me that the built kernel module can't be loaded. there were also warnings about missing symbols at compile time. this is the relevant part of dmesg-output when loading the driver: nvidia: Unknown symbol pv_mmu_ops nvidia: Unknown symbol pv_cpu_ops nvidia: Unknown symbol pv_irq_ops nvidia: Unknown symbol pv_lock_ops it seems, the above symbols are missing. this was not the case with 2.6.27.12-1. i had to downgrade kernel to latest available 2.6.27.7-9 from oss-repo. with this version building the nvidia driver also was no problem. right now i am writing this mail with this setup. there must have been some changes between 2.6.27.12-1 and 2.6.27.13-2 which have something to do with these missing symbols. does anybody know anything about this error? -- einen schönen Tag noch DI Rainer Klier Und bitte keine TOFU-Mails (http://de.wikipedia.org/wiki/TOFU) -- To unsubscribe, e-mail: opensuse-kernel+unsubscribe(a)opensuse.org For additional commands, e-mail: opensuse-kernel+help(a)opensuse.org

[opensuse-kernel] KOTD 2.6.27.12-HEAD_20090122183653_0d7eb945-default
by Markus Koßmann 26 Jan '09

26 Jan '09

When booting 2.6.27.12-HEAD_20090122183653_0d7eb945-default x86_64 on my system the system freezes immediately with black screen. With both normal and safe settings. Nothing on the screen, nothing in the logs. 2.6.27.12- HEAD_20090120200141_5646759d works fine on that system. How to get useful information for a bug report in that case ? -- To unsubscribe, e-mail: opensuse-kernel+unsubscribe(a)opensuse.org For additional commands, e-mail: opensuse-kernel+help(a)opensuse.org

[opensuse-kernel] problems with wireless iwlagn
by Volker Krueger 21 Jan '09

21 Jan '09

Hi, I have problems with my wireless driver iwlagn. all I can say is that it is not possible to log onto our university network. with Ubuntu, however, I _can_ long on. I was told that Ubuntu has patched that driver. So, my problem seems to be a known problem. Does anyone know anything about this? best, Volker -- To unsubscribe, e-mail: opensuse-kernel+unsubscribe(a)opensuse.org For additional commands, e-mail: opensuse-kernel+help(a)opensuse.org

[opensuse-kernel] 2.6.29-rc2 update
by Jeff Mahoney 19 Jan '09

19 Jan '09

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi all - Just a quick FYI that I've updated and renamed the v2.6.28-staging tree. It is now known as the HEAD_STAGING tree. The HEAD_STAGING directory will replace the v2.6.28-staging directory on KOTD. The tree is now at 2.6.29-rc2. As usual for an early RC, there are some caveats: - - Xen is still disabled. - - AppArmor is disabled. - - KDB is disabled. It boots on my x86-64 system and I'm waiting for the build logs to tell me where it fails. As those logs arrive, I'll update the tree. This is the bleeding edge, folks. :) - -Jeff - -- Jeff Mahoney SUSE Labs -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.9 (GNU/Linux) Comment: Using GnuPG with SUSE - http://enigmail.mozdev.org iEYEARECAAYFAkly09wACgkQLPWxlyuTD7LRrQCfUAFxXzr4q3tK9YtP5kcA/dpJ 1RcAn2fGAHPG44WqL4pAwvAqCJAOXB6A =UTCz -----END PGP SIGNATURE----- -- To unsubscribe, e-mail: opensuse-kernel+unsubscribe(a)opensuse.org For additional commands, e-mail: opensuse-kernel+help(a)opensuse.org

[opensuse-kernel] Creating a new kernel flavor
by Matt Sealey 18 Jan '09

18 Jan '09

Hi, We're working on creating a new kernel flavor here so we can maintain a few patches against the standard -default kernel without trashing peoples' installations (i.e. while you can't have -default and -genesi at the same time because of the cleanup in post-install, at least if it stops working or there's a weird bug, you can still go back to -default without forcing packages, and there would be no package conflicts if someone added our repo, and it had a higher version of -default..) However I've stumbled across some real weirdness in kernel-source.src - which I then gather builds kernel-source.ppc which then can be used somehow to build kernel-genesi.ppc and .src. For instance, every kernel-$flavor.spec seems to be built from the same source somewhere, with identical changelogs and 99% identical code (the difference being the swapping of the flavor in many places, but that's it). So far I have just hacked up a kernel-genesi.spec myself which is building fine now, but I wondered, where do these files get generated and how can I make my kernel build take part in this process to build an automated spec file? Modifying config.conf, series.conf, adding patches is something I've been doing for a while so that has never been a problem to make a custom kernel-default, I would just like to move away from it. Is there any special documentation or a cheat sheet for how to make a new kernel flavor? What was the process to create kernel-ps3, for example, a few versions ago, and how does it get maintained with the rest? -- Matt Sealey <matt(a)genesi-usa.com> Genesi, Manager, Developer Relations -- To unsubscribe, e-mail: opensuse-kernel+unsubscribe(a)opensuse.org For additional commands, e-mail: opensuse-kernel+help(a)opensuse.org

[opensuse-kernel] 2.6.27 kernel for 11.0?
by Felix Miata 16 Jan '09

16 Jan '09

http://download.opensuse.org/repositories/home:/ilya_41/openSUSE_11.0/i586/ has these. Anyone know reasons for or against trying to use any of them on a production server? My problem is https://bugzilla.novell.com/show_bug.cgi?id=406035 which is marked fixed, but for 11.1, not 11.0. For the reasons listed in the thread http://lists.opensuse.org/opensuse/2008-12/msg01969.html I'd rather not be forced into 11.1 if possible. Can anyone tell why the above bug's owner claims its fix amounts to a new feature preventing fix's inclusion in 11.0 updates? I installed .27 on an old ICH4 P4 GX260 PATA host I use for testing. Its 11.0 partition is on hda21, and so using piix legacy driver. After a while it locked hard while in runlevel 3. Then I installed .27 on a newer ICH7 P4 RAID1 SATA host "big31" using libata (not my new ICH8 server, but similar in being almost as new). So far big31 hasn't done the same. Can anyone look in the boot.msg & messages logs in http://fm.no-ip.com/tmp/SUSE/110/ and tell me if the lockup might have been due to the .27 kernel rather than piix driver or hardware failure? -- "Train a child in the way he should go, and when he is old he will not turn from it."

If it's RO and you can't alter it, then there wouldn't seem to be any end user benefit apart from casual browsing, to overcome the "if it ain't broke don't fix it". Just developer benefit through supporting fewer formats. This is what led me to believe, SquashFS was permitting easier modification, I think I misunderstood that. 2009/1/14 Matt Sealey <matt(a)genesi-usa.com>: > >> What advantages do you know of? > > Appending files is a breeze compared to a cpio archive.

Though mounting, copying to disk, and then re-building the formatted file, is more like making iso files. "zcat initrd | cpio -id" and then rebuilding, wasn't obvious enough to get suggested when I had an issue with replacing the driver with mkinintrd on a live system. It is still a nice to have, as udev generating it's own module list, to be combined with INITRD_MODULES, doesn't make the change methodology clear to the sysadmin. -- To unsubscribe, e-mail: opensuse-kernel+unsubscribe(a)opensuse.org For additional commands, e-mail: opensuse-kernel+help(a)opensuse.org
