Old code aligned it to 8-bytes. There is 50/50-chance of it also being 16-byte aligned. So it ended up being both 8-byte and 16-byte aligned. > Also, how do you *know* something is broken right now? I haven't spotted brokenness in Linux microcode loader other than that small alignment issue. However, I can confirm that there are 2 microcode updates newer than what my laptop computer's latest BIOS includes. Both newer ones (20191115 and 20191112) are unstable on my laptop computer i5-7200U (fam 6 model 142 step 9 pf 0x80). Hard lockups with both of them. Back to BIOS microcode for now. -- Jari Ruusu 4096R/8132F189 12D6 4C3A DCDA 0AA4 27BD ACDF F073 3C80 8132 F189
