A few weeks ago I clean installed 20.04.1 and at the same time I switched to the Brave Browser. As I was frequently experiencing my system freezing, and by freezing I mean I could still move the mouse cursor but nothing would respond, I assumed the issue was the Brave Browser and I found on their git a history of a similar issue. I disabled hardware acceleration in Brave, which is a reported workaround, but when that did not help I switched back to Chrome.
Unfortunately even using the latest version of Chrome, the issue is ongoing. When the system becomes unresponsive it stays so for approximately 30 seconds to 1 minute. A few times I have had to use REISUB or when that did not work cold reboot, but the majority of the time it just starts responding again. I have tried to completely mirror the same clean install setup and packages on my Dell XPS 13 9360, which does not experience the same issue.
As I post this morning some of the lockups I have experienced today have allowed me to switch window, for instance terminal would freeze but I could switch to a non-responsive Chrome or vice versa.
Please find several logs below which were created after the issue occurred and immediately after my system started responding again. Often I am not doing anything especially heavy, just Chrome open with 4 or 5 tabs. My system is an i5-4690K, GTX 970, 8GB of RAM, Samsung SSD 840 EVO Basic SATA. I am using the Nvidia driver 450.66.
Searching for a similar error to one of those that occurred a lot this morning: 06:13:58 fuser: Cannot stat file /proc/2733/fd/1023: Permission denied
(the path after /proc/ varies) I found this thread Getting strange errors while downloading mysql and although I was not installing MySQL and I do not have it installed but in case it could help I followed some of the troubleshooting steps: libaio1 was installed but I input sudo apt-get install libaio1 libaio-dev
, sudo apt install aptitude
, sudo aptitude update
, sudo aptitude upgrade
, and rebooted. Unfortunately the same issue occurs, and as you will see from the latter 4 logs this happened as many times over 34 minutes, and those are just the ones I generated logs for and the count is more like twice that. Since rebooting about 30 minutes ago it has only happened twice so far but I expect it to continue throughout the day as normal.

Could you please review my logs and let me know if there is something that may suggest how to resolve this?
