Created attachment 257075 [details] lspci and "cat /proc/cpuinfo" output I have issues with my HP 250 G5 laptop, similar with issues described here: https://bugzilla.kernel.org/show_bug.cgi?id=109051 and here: https://bugzilla.kernel.org/show_bug.cgi?id=193011 My laptop suffers from random freezes and the only way to cure it seems to add intel_idle.max_cstate=1 to boot parameters.
is there a way to make the freezes *LESS* random and occur *MORE* frequently? what is the highest number N in "intel_idle.max_cstate=N" where this system is stable?

Regrding more frequently. It happens often while watching HTML5 videos. Also it may freeze if notebook is left untouched for long time, even half of an hour. Regarding highest N, I will check and report.
Hello, I updated kernel to version 4.4.0-83-generic, which came with ubuntu updates. I'm using the laptop for several days since, and can confirm that it didn't freeze even without "intel_idle.max_cstate". Suppose it was fixed someway. Great thanks to everyone, who is engaged.
