I’ve got an annoying problem with random freezes. Can someone please help?
While watching video in Brave browser (based on Chrome) on my Pop!_OS 19.10 with Nvidia 2070 Super, it freezes. The video hangs, sound continues, otherwise not usable. I tried to get into terminal to rescue something, but no luck. Unplugged keyboard and mouse, no luck. So I can only hard-reset the machine.
In the Kernel log you can see “segfault” in Brave:
