Also, it might be safer to disable intel_idle and intel_pstate drivers, e.g. pass options
intel_idle.max_cstate=0 intel_pstate=disable
I'll give these options a try before installing the newer kernel.
Setting these kernel parameters had no effect, the system just stopped responding and needed a power cycle. Unfortunately kdump didn't capture anything.
You may try also i915-quickfix KMP in OBS home:tiwai:bnc974884 repo. It has a couple of backports. Just install i915-quickfix-kmp-default.rpm from that repo, reboot and retest.
Installing this generated a package dependency problem nothing provides ksym(default:cpu_tss) = 3356b90b solution 1: don't install solution 2: break i915-quickfix KMP by ignoring dependency What's the best course of action with this? Carl
Speaking of kdump: you should test kdump manually beforehand, just to check whether it works at all. YaST2 kdump setup is often too tight and fails when KMS is used. Run echo -n c > /proc/sysrq-trigger and see whether you get a proper kdump.
