Dear Sir, I used the workaround from bug 994921 and rebooted the system. I ran about one hour and the same type of Hangup of the System occurred. Doing my normal Alt + PrtScrn, Alt + CREISUB, I thus got my system back. I then ran the "sudo ubuntu-bug xxxx.crash" command and created bug # 1879585 Please see that Report for what I was doing at the time of the Hangup. Any additional information that I can give to you, I will be happy to. Thank you for your effort in solving this very pesky problem. Frank Krauss
