the Oops occurs on Shutdown... and not every time! (hence need some time to verify it no longer happens) I made the mistake of using Yast update from list, I guess it didn't work because the update suffix was higher. Fixed now. chorler@linux-tn2c:~> uname -r 4.12.14-lp151.1.gba5e5e8-default I'll update the bug report with latest info next week (after testing!)
