Got the same problem when using my Lenovo T410. System freezes randomly, found no alarming lines in syslog except for missing i915 firmware.
W: Possible missing firmware /lib/firmware/i915/kbl_guc_ver9_14.bin for module i915 W: Possible missing firmware /lib/firmware/i915/bxt_guc_ver8_7.bin for module i915 Since I updated to zesty, it seems to happen less often. -- You received this bug notification because you are a member of Kubuntu Bugs, which is subscribed to kdebase in Ubuntu. https://bugs.launchpad.net/bugs/1645503 Title: System crashes randomly when Konsole is active To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/kdebase/+bug/1645503/+subscriptions -- kubuntu-bugs mailing list kubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/kubuntu-bugs
