On Ubuntu 17.04 zesty the proposed microcode package installs and loads fine: $ dpkg-query -W intel-microcode intel-microcode 3.20170511.1~ubuntu17.04.0 $ grep -E 'model|stepping' /proc/cpuinfo | sort -u model : 78 model name : Intel(R) Core(TM) i7-6600U CPU @ 2.60GHz stepping : 3 $ journalctl -k|grep microcode Jul 01 14:21:47 thunder kernel: microcode: microcode updated early to revision 0xba, date = 2017-04-09 Jul 01 14:21:47 thunder kernel: microcode: sig=0x406e3, pf=0x80, revision=0xba Jul 01 14:21:47 thunder kernel: microcode: Microcode Update Driver: v2.2.
I have confirmed that it also fixes the original testcase from the OCaml bugtracker (with the old microcode it was crashing quite soon). $ eval $(opam config env) The OCaml toplevel, version 4.04.1 $ while ocamlfind opt -c -g -bin-annot -ccopt -g -ccopt -O2 -ccopt -Wextra -ccopt '-Wstrict-overflow=5' -thread -w +a-4-40..42-44-45-48-58 -w -27-32 -package extprot test.ml -o test.cmx; do echo "ok"; done ok ok ok ok ok ... Running the perl script posted on the Debian mailing list shows all OK too: cpu 0: Your CPU is affected, but your microcode is new enough cpu 1: Your CPU is affected, but your microcode is new enough cpu 2: Your CPU is affected, but your microcode is new enough cpu 3: Your CPU is affected, but your microcode is new enough Note: I've been using the 20170511 version of microcode using the package from artful for about 6 days, and haven't noticed any problems. ** Tags removed: verification-needed-zesty ** Tags added: verification-done-zesty -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1700373 Title: intel-microcode is out of date, version 20170511 fixes errata on 6th and 7th generation platforms To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/intel-microcode/+bug/1700373/+subscriptions -- ubuntu-bugs mailing list firstname.lastname@example.org https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
