This is what it said when intel-microcode 3.20160607.1 dropped and it stopped booting. Jun 26 22:44:41 carbon kernel: [ 1.722592] microcode: CPU0 sig=0x406e3, pf=0x80, revision=0x74 Jun 26 22:44:41 carbon kernel: [ 1.722657] microcode: CPU1 sig=0x406e3, pf=0x80, revision=0x74 Jun 26 22:44:41 carbon kernel: [ 1.722767] microcode: CPU2 sig=0x406e3, pf=0x80, revision=0x74 Jun 26 22:44:41 carbon kernel: [ 1.722849] microcode: CPU3 sig=0x406e3, pf=0x80, revision=0x74 I had an older 4.6-trunk kernel on the system as well from experimental that did not get the initramfs hook called on it when intel-microcode updated. So that one continued to boot while I couldn't use the kernel that did until I updated the bios. I also tried "update-initramfs -u -k 4.6.0-1-amd64" many times to fix it with no luck. Only after updating the BIOS did it boot with the previously generated initramfs.
