As suggested by @aleksfadini in #589, it seems that `modprobe.blacklist=intel_lpss_pci` is the minimal workaround - this module is marked as `built-in` in my Kernel configuration, however. I will test this...

Another issue came up after checking power-draw on s-tui with a 2-minute stress run, the processors sustained at around ~2.4GHz frequency with a power draw of ~25W. However, as soon...

@aleksfadini Maybe, but I think there needs to be more investigation (i.e. trying to reproduce that on Windows).

Speaking of which, I was just checking my `dmesg` and was greeted by a large amount of Intel DRM related errors... ``` [ 3863.983087] [drm:intel_pipe_update_end [i915]] *ERROR* Atomic update failure...

@aleksfadini Can confirm that `modprobe.blacklist=intel_lpss_pci` is a valid workaround.
