nitial workaround to the problems of power regression is to add “pcie_aspm=force” besides existing GRUB boot arguments, this did help to some point but what really helped in both cases was also adding “i915.i915_enable_rc6=1” or at least I thought so since this line only applies to Sandy Bridge (i3/i5/i7) and latter. In the end my “/etc/default/grub” looks like:
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash pcie_aspm=force i915.i915_enable_rc6=1"
and make sure you run “update-grub” after making these changes.
