Description Korner 2020-04-14 19:21:12 UTC

I have UHD620 igpu housed on i5 8250U and from many many tests when i put computer under high load or anything other than basic things like browsing internet or general usage it will freeze entire system where i have to force shutdown the machine.
This all happens on kernels that are 5.x and above, and they do not happen on anything that is kernel 4.x, i have tried these boot options `intel_idle.max_cstate=1 i915.enable_dc=0`  but unfortunately they did not help.
This bug results in users with same issue like this be forced to use old kernels.

I can confirm that the error also occurs on Intel i5-8365U (Dell Latitude 7400, Ubuntu 20.04 with kernel 5.4.0-31(, also tested on 5.6.13). I have random freezes with no apparent reason once every 2 to 3 days, sometimes even once a day. No system logs, the system just stops. I did memory test and stress tests. The freezes happen randomly, are not system load or temperature dependent.

How about disabling i915 module? After boot up, you can unload it via
rmmod i915

In my case motherboard replacement fixed the issue so far. No crash since a month now.
