Hello All,
I have a brand new HP Z240 workstation running Leap and it randomly freezes, becomes fully unresponsive, both locally and over the network, and I'm forced to power cycle the system. This has been happening multiple time a day with no rime or reason, sometimes it's sitting idle after a reboot, reading email, whatever. The most frustrating part about it is there's never anything in the logs to indicate a reason for this.
It's the default installation, BTRFS partitioning scheme, XFS for /home, KDE5, nothing crazy at all.
I've installed and configured kdump with the hope it will be able to provide some insight after the next occurrence, but given there are no kernel crash messages in the logs it's hard to say whether it will help. I guess time will tell.
Does anyone have any thoughts further debugging this type of an issue?
It's a Skylake system, right? Skylake graphics is weakly supported by Leap kernel. Try the latest kernel in OBS Kernel:openSUSE-42.1 repo, at least. I guess 4.1.20 was released in the update repo recently, too, so this should be OK, too.
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
In anyway, feel free to open the bug report. Don't forget to attach the output of "hwinfo --all" and the kernel messages (dmesg output) for a while after a fresh boot.

I saw at least one of these shipping with a NVIDIA Quadro graphics card of which we never had a smooth experience with under Linux at my previous employer (Most were pulled out and replaced with much cheeper GeForce cards which did the job really well. Having said that if you do have one of these cards the latest NVIDIA proprietary drivers might work better. -- Simon Lees (Simotek) http://simotek.net Emergency Update Team keybase.io/simotek SUSE Linux Adeliade Australia, UTC+9:30 GPG Fingerprint: 5B87 DB9D 88DC F606 E489 CEC5 0922 C246 02F0 014B
