Wasn't happening before with ubuntu 18.04 but happens with ubuntu 20.04. Also some side notes: * It only happens with chrome-like instances (like Google Chrome, Chromium, Brave, Electron) open * Sometimes it does recover after 10 minutes frozen (very few times, but it does sometimes) * Happens at least once per day (I'm using for two weeks now, and everyday it freezes at least once, and sometimes it gets really annoying) * I use XFCE4 with Compton The laptop is an Avell (Clevo Rebrand) with an i7 6820HK. The temperatures are always low before freezing, but after it freezes all coolers get maximum (and gpu temp reache about 70 degrees celsius) -- 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/1861294 Title: Gpu watchdog segfault and video+kbd+mouse freeze on optiplex 7060 intel gpu Status in linux package in Ubuntu: Incomplete Bug description: Running up-to-date Ubuntu-18.04.3 with kernel 5.3.0-26 on a Dell Optiplex 7060 with an i7-8700 CPU and Intel UHD Graphics 630 (Coffeelake 3x8 GT2).

After a cold reset I didn't see any other GpuWatchdog messages in journalctl. Ubuntu applied a BIOS firmware update before the first freeze, so my BIOS was updated as part of the cold reset I did. Not sure if this is relevant to reproducing the freeze.
