[opensuse-kernel] Kernel 2.6.34-rc2 hangs on one of three systems
by Johannes Obermayr 27 Mar '10

27 Mar '10

Hi, I installed Kernel 2.6.34-rc2 on three systems (all 11.2 with Kernel:HEAD repo). Two of them do not have any problems - they seem even a bit faster compared to 2.6.33. But on one system (MSI K7T Turbo [MS-6330] with a AMD Duron 900) the kernel hangs at an early stage (all flavors). It is so early that I cannot provide any logs and only the reset button works then. Can you please tell me what I have to do for providing useful information? Btw. I am not really familiar with kexec and kdump ... Thanks.

[opensuse-kernel] v2.6.34 branch
by Jeff Mahoney 10 Mar '10

10 Mar '10

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi all - I've just created a new branch called v2.6.34. It contains the openSUSE patch set on top of 2.6.34-rc1. As per my usual process, I'll merge this into the master branch at rc2 or rc3. For now, you're welcome to test on this separate branch. It boots on my development node, but that's as much testing as I've given it. As usual for a first merge, Xen is disabled until those patches can be brought up to date. Also, for some time we've been running into issues where config options were changed during a version bump or for another reason but the documentation is lost. For single config value changes, it's generally (but not always) enough to look in the git log. For massive changes, like those associated with an -rc1 merge, that becomes very noisy, very quickly. So, for this merge, I created a doc/config-options.changes file that documents what config values were changed and why a certain choice was made. For drivers that are built as modules, there's no explanation needed. Michal - When you get a chance, can you set this up for building and publishing? Thanks! - -Jeff - -- Jeff Mahoney SUSE Labs -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.13 (GNU/Linux) Comment: Using GnuPG with SUSE - http://enigmail.mozdev.org/ iEYEARECAAYFAkuW9VQACgkQLPWxlyuTD7IEjgCeIB2blIzmqVP28WPDdDsjsQMN g+QAnjpK5qoo7bLf/R8W/8Tii3KKdNws =EIt1 -----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] iwl3945 issue on openSUSE 11.3 M3
by Andi Sugandi 09 Mar '10

09 Mar '10

Hi listmates, I'm Acer and KDE 4 user, and this machine has wireless adapter: 03:00.0 Network controller: Intel Corporation PRO/Wireless 3945ABG [Golan] Network Connection (rev 02) openSUSE 11.2 does the right job to automatically bring the Wlan0 start (the led is on) right after KDE is up, but different on openSUSE 11.3 M3 (and M2), the led is off and (of course) the wireless connection seems disable (eth0 still works though). To solve this issue, I should first: 'service network restart' , and then 'modprobe -r iwl3945 && modprobe iwl3945' . My enabled repositories: http://download.opensuse.org/factory/repo/oss/ http://download.opensuse.org/factory/repo/non-oss/ The used kernel version: 2.6.33-5-desktop Does anyone have this issue too? Should i file a bug?

Greetings. I am getting a warning from rpmlint that /boot/vmlinux-2.6.33-0-default.gz is packaged twice: once by kernel-default and kernel-default-devel. That should probably be corrected. -- To unsubscribe, e-mail: opensuse-kernel+unsubscribe(a)opensuse.org For additional commands, e-mail: opensuse-kernel+help(a)opensuse.org

[opensuse-kernel] novfs: replace MUTEX by sema functions

Avoid old MUTEX macros and use sema instead, which works for both default and RT kernels.

[opensuse-kernel] 4k sector size problems in linux
by Stephen Shaw 02 Mar '10

02 Mar '10

I was approach by daniel while at the recent scale8x conference and was asked to get in touch with follow novell engineers that work on our partitioning tool with regard to 4k sectors size problems. Daniel is with western digital and was hoping to work with us to make sure these issues are resolved. I'll let him go into more detail.
