Thanks for looking into this @kaihengfeng. I will try that and post results.
I have been running the system for a few days without running into the error. The usual symptom I see when I run into the issue is that all the icons on the desktop becomes a blank icon / broken icon. So all the icons in the favorites bar and the notification area becomes same icon. In addition to the above change with the filessytem remount rw, I had also turned off fast boot in Windows. I hoped that would stop windows from setting unnecessary hardware settings when it shuts down. However I ran into the same blank icon state today. The system was in standby mode. I had closed the laptop (not shutdown) yesterday and opened it today. I worked on the system for a few minutes and then this crash happened. I tried to cat /var/syslog but that did not work. What commands should I try next time I run into this state? I have uploaded /var/log/syslog here. I am going to also make the change suggested by kaihengfeng and will keep the thread posted. ** Attachment added: "Syslog from the recent crash." https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1927866/+attachment/5499978/+files/syslog -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1927866 Title: Root filesystem becomes readonly frequenty freezing system To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1927866/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
