0x74 microcode, released 3/15/16, and SGX disabled. Unfortunately, I can't flash newer UEFI if they put one out (still the most recent for it as of this posting) because the updater is Windows only (although I did flash the most recent one before wiping the drive, and have a Clonezilla backup of the Windows install if I absolutely have to). At least hopefully there'll eventually be microcode files I can early boot load.
EDIT: At least this is less bad than when I got a Broadwell i7 5700hq laptop last year and the microcode-based TSX issues were so bad I could only boot Fedora 22 for a month stably (it would crash under any load) until MSI (the ones I bought it from) were the first out with a fixed microcode update. (And their updater actually works from the UEFI loading off a USB stick). Intel's just awful anymore, but not like we really have any alternatives, given how bad AMD CPUs are for a lot of things anymore.
EDIT: Seriously, TSX was properly disabled under Haswell for a year at that point! Why was Broadwell shipping with it enabled and faulty? Did they not even check?
