I have had about 3 lockups on my new (used) Lenovo L420. The symptoms are that the system freezes with no responses to either the mouse or the keyboard. in the most recent incident I was viewing the list of installed sw in the Ubuntu software GUI. This time I waited for 29 minutes before pressing the power switch. During that time I saw no signs of life-the time display text in the menu bar did not change. After restarting, before the login screen appeared there were a number of lines of text at the top of the screen which went by to fast to read. On a more normal boot two lines appear, also too brief to read. I took a video of the two lines. They say "? is not active yet, using direct activation during sysinit /???/??gg??/ubuntu--root:clean,237000/7536640 files, 3272140/39119936 blocks" I think I got most of that right; video is hard to read.
Immediately on rebooting after the crash I saved the sys.log file. The lines just before and just after the 29 minute break are: Jun 16 20:56:19 denis-ThinkPad-L420 systemd[1]: Started Network Manager Script Dispatcher Service.

Are there any other diagnostics which might be useful? The os is ubuntu 16.04, 8G ram, hard drive is 128G SSD, swap is turned off. Fresh, recent install of os. uname -r yields 4.4.0-24-generic Thanks, -Denis _______________________________________________ PLUG mailing list [email protected] http://lists.pdxlinux.org/mailman/listinfo/plug
