Dear Sir, I wish to thank you for your suggestion about using a different and older Nucleus. I didn't understand initially about the difference between the 4.x and 5.x Versions.
After I did research on them, I installed the 4.15.0 release. It has been running perfectly for the past week so I believe that is the correct solution to my problems of the System hanging periodically. I think that maybe it is because my System was built for me over 10+ years ago. It probably dosn't support the HWE code of the 5.x Series. I will close out this bug and also three other bugs which likewise have no longer shown up. Thank you again for your excellent suggestion that has cleared up these serious problems on my Bionic Beaver System. Yours truly, Frank Krauss +++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ On Tue, 2020-05-12 at 07:10 +0000, Kai-Heng Feng wrote: > Does the GA kernel (i.e. 4.15) have this issue? > > ** Changed in: linux (Ubuntu) > Status: Confirmed => Incomplete > -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1877890 Title: System Hangs when trying to kill a Window Status in linux package in Ubuntu: Incomplete Bug description: Dear Sirs, I'm a long term user of Ubuntu, I run a Client/Server system that my clients expect to be very stable. 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.
