Although I have had crashes of my TW for a longer period of time, TW began working more decent since last series of updates. Since I was still not feeling too happy with my machine I spend some time looking into error messages. This finally lead me to bug 960848. I have looked through the correspondence and found that there is still no solution. An temp solution which was mentioned was to look at kdump and see with "echo c > /proc/sysrq-trigger" if its functioning. That test gave me a kernel panic. Raising the memory reserved in kdump in Yast found me on a surge where to find kdump and how to change the values. no luck. Same with an advice to add {1915.semaphores=0 i915.enable_rc6=0) as boot option. Since grub2 I am totally lost at editing boot options. Need some practical help there. As to following above bug I remember from the past that it was quit easy to add yourself on the mailing list for a bug. Did not find how. Must have overlooked that possibility. -- Linux User 183145 using KDE4 Tumbleweed on a Pentium IV , powered by openSUSE 20160208 (x86_64) Kernel: 4.4.1-3.g2b16688-default KDE Development Platform: 4.14.16 11:18am up 1:10, 2 users, load average: 0.73, 0.99, 1.24 -- To unsubscribe, e-mail: opensuse-factory+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse-factory+owner@opensuse.org
