Tested successfully on Ideapad with Core i3-6006U. The microcode revision is now back to 0xd6, as with microcode_ctl-2.1-37.fc32.

It should be noted here that Intel recently withdrew revision 0xdc for most Skylake processors because many users reported failed boots. Without that update there is however no mitigation for SRBDS on Skylake.

This update has been pushed to testing.
