[opensuse-kernel] kernel 3.8 and 3.9 crash/reboot
hi, since kernel 3.8 i have the following problem with my hp compaq 8710w notebook: https://bugzilla.novell.com/show_bug.cgi?id=807312 it reboots itself after some time with now noticeable error. does anybody of you also use a 8710w notebook and runs kernel 3.8 or 3.9 without problems? kernel 3.7.10 is working fine. or does anybody know this problem? -- Rainer Klier Research & Development xyzmo Software GmbH, SIGNificant E-Signature Solutions A-4052 Ansfelden, Haiderstraße 23 Tel.: +43 7229 88060-0, E-Mail: rainer.klier@xyzmo.com N�����r��y隊Z)z{.���w���칻�&ޢ��������'��-���w�zf���^�ˬzG���~� ޮ�^�ˬz��

does anybody of you also use a 8710w notebook and runs kernel 3.8 or 3.9 without problems?
kernel 3.7.10 is working fine.
or does anybody know this problem?
I don't know about the problem, but I would suspect a overheating problem. Did you notice any fan spinning difference between kernel 3.7 and kernel 3.8 (for example fan spinning with 3.7 and no longer with 3.8)? Install sensors and see if it reports some temperature value. Maybe run sensors-detect to get additional temperature sensors (from the coretemp driver most probably.) Compare the temperatures (and any thermal setting you can find) between kernels 3.7 and 3.8. Also compare powertop output between kernels, to make sure that C states and cpufreq are working the same. -- Jean Delvare Suse L3 -- To unsubscribe, e-mail: opensuse-kernel+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse-kernel+owner@opensuse.org

YES! you are right! at 3.7 the fan runs the whole time. at 3.8/3.9 it starts and stops from time to time, and is off most of the time. this is one of the first things i noticed, when i tried 3.8 the first time. so it sounds very plausible to me, that this can be the problem.

thanks for the tips. do you know a way to force the fan to run the whole time? with 3.7 it does it automatically, but not with 3.8/3.9. if i know how to control the fan, ich can force it to work the whole time with 3.8/3.9. -- Rainer Klier Research & Development xyzmo Software GmbH, SIGNificant E-Signature Solutions A-4052 Ansfelden, Haiderstraße 23 Tel.: +43 7229 88060-0, E-Mail: rainer.klier@xyzmo.com
