[opensuse] Kernel panics after recent updates
Hi all, I have Leap 42.1 installed on a set of servers that are used for hosting KVM virtual machines. Since 12 June, one of those servers started to reboot unexpectedly every 2-4 hours. Until then it had no uptime issues. Initially I thought this was a hardware failure, so I started looking for disk, memory errors etc. No problems found. Then I realized that this machine was the last one patched with updates... so I re-installed Leap from scratch. Result: The server works as expected again. Then I did the following test: I updated another server. Result: this server started rebooting.... I am afraid there is something broken in libvirt or in the recent kernel updates. This is part of the crash log I get: │kernel │NMI watchdog: BUG: soft lockup - CPU#1 stuck for 23s!
