[opensuse-kernel] Backport rtl8187 fixes to v2.6.27
by Carlos Goncalves 04 Aug '09

04 Aug '09

Hi, Any chance we could backport rtl8187 fixes introduced on kernel 2.6.3.0 that fixes weak signal detection and bad performance? I've this device (0bda:8187) and running kernel 2.6.27.25-0.1-default (openSUSE 11.1), signal is at 15/100 and after a few seconds after setting it up speed drops to ~1Mbps and stays there until 'rcnetwork restart' (driver restart?).

[opensuse-kernel] Optimizing i386 kernel-default for desktop?
by Takashi Iwai 04 Aug '09

04 Aug '09

Hi, just looking through SUSE kernel config files, I found that i386/default setup is still for the server, CGROUP=y, PREEMPT=n, etc. Can it be changed to the ones like kernel-desktop? According to bug #526780, kernel-desktop actually helps to improve the audio issue (mostly PA). Since kernel-default is basically for old machines (thus it's the only kernel with ISA support), we don't have to keep the server optimizations there. thanks, Takashi -- To unsubscribe, e-mail: opensuse-kernel+unsubscribe(a)opensuse.org For additional commands, e-mail: opensuse-kernel+help(a)opensuse.org

[opensuse-kernel] kernel & BIOS report (incorrectly?) different current/available speeds for overclocked CPU
by PGNet Dev 04 Aug '09

04 Aug '09

i've built up a new openSUSE server on a mobo: ASUS M3A78-CM, BIOS r1903 cpu: AMD 2.8GHz Phenom II X4 920 (Black) @ BIOS, i've overclocked the CPU by 33% from 2.8Hz -> 1.33 x 2.*8 = 3.7GHz. booting to OS, the reported(/available) CPU freq is NOT that which the BIOS reports. questions: (1) is this a bug, or expected behavior for OC'ing? (2) if a bug, is it in kernel, or BIOS? (3) if not a bug, how does one monitor _actual_ CPU speed in openSUSE? details ... uname -a Linux server 2.6.27.25-0.1-default #1 SMP 2009-07-01 15:37:09 +0200 x86_64 x86_64 x86_64 GNU/Linux checking, cpufreq-info cpufrequtils 004: cpufreq-info (C) Dominik Brodowski 2004-2006 Report errors and bugs to http://bugs.opensuse.org, please. analyzing CPU 0: driver: powernow-k8 CPUs which need to switch frequency at the same time: 0 hardware limits: 800 MHz - 2.80 GHz available frequency steps: 2.80 GHz, 2.10 GHz, 1.60 GHz, 800 MHz available cpufreq governors: conservative, userspace, powersave, ondemand, performance current policy: frequency should be within 800 MHz and 2.80 GHz.

After updating to the .31rc4 my X doesn't start (but it works in failsafe); if I run sax2 -r it freezes (the screen, I can still input stuff even though it's not shown), but here's the error log: http://francis.giannaros.org/temp/SaX.log -- any ideas?

[opensuse-kernel] Question on Kernel 2.6.27.x for 11.0
by Anshul Jain 03 Aug '09

03 Aug '09

Hi, The 11.0 version officially uses the 2.6.25.x kernel series, however I'd like to upgrade/try out the 2.6.27.x or newer series for 11.0. Can I use 11.1 Kernels and install it on an 11.0 system?
