I ran under Trust Tahr for a long while with great success and no Hangups at all. I recently upgraded to Bionic Beaver and I find that I have a number of Hangups. They seem to occur mostly when switching between different users. The latest one that occurred last night that I want to show you here was caused by something else. I was watching a video from Youtube under Firefox. At the end of it I clicked the upper right hand button of the window to kill the screen. At this point the system froze on me. I could move the mouse around but none of the keys worked. I used the SysrRq - Magic Key combination to get the following information ALT + PrtScrn, ALT + CREISUB The system re-booted and gave me the following files in /var/crash 4096 May 9 23:38 202005092338 349 May 10 11:01 kexec_cmd 25387 May 9 23:39 linux-image-5.3.0-51-generic-202005092338.crash 69696 May 9 23:38 dmesg.202005092338 291014103 May 9 23:38 dump.202005092338 I used the crash program with the Symbols file and in the backtrace section under the exception line it says: exception RIP mwait_idle+132 in the disassembly of mwait_idle the line at +132 is mov %gs:0x72774cb4(%rip),%r12d # 0x10350 Any information that I can supply to you I will be glad to in order to aid you in solving this problem. I'm fairly computer literate and so I can follow any directions that you want to give to me. I have enjoyed using Ubutnu for many years but I do need a Stable environment for my Development work and for my users satisfaction.
