My 5420s (~50 of them out of a ~200 laptop fleet) with an i5-1135g7 on Fedora Rawhide and CentOS 7 (with mainline kernel) don't seem to be affected by this, BUT

My 5420s (~50 of them out of a ~200 laptop fleet) with an i5-1135g7 on Fedora Rawhide and CentOS 7 (with mainline kernel) don't seem to be affected by this, BUT I have a couple 5490s with 8656u CPUs that are. I should note that the 8656u CPUs have been nothing but trouble (multiple mobo replacements and still have suspend issues).
