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.
Yes this is a Skylack system and it's running the 4.1.20-11-default, and I see that 4.1.21-2.1 is the version in OBS Kernel:openSUSE-42.1 .
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.
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 was planning on this but wanted to wait until I had a few work-arounds.
