This really is a v2 of this patch: https://patchwork.kernel.org/patch/11663271/ with an extra preceding cleanup patch to avoid making unrelated changes in the [2/2].I applied this series along with [PATCH] cpufreq: intel_pstate: Fix EPP setting via sysfs in active mode on 5.8 latest master (On top of raw epp patchset).Hi Srinivas,
Hi Doug,
Would you be kind enough to provide a "git log --oneline" output of what you did.

I have been trying unsuccessfully to apply the patches, so somewhere I obviously missed something.quoted
When intel_pstate=passive from kernel command line then it is fine, no crash. But switch dynamically, crashed:I'll try to repeat, if I can get an actual kernel.quoted
Attached crash.txt. I may need to try your linux-pm tree.I also tried the linux-pm tree, same. ... Doug
