Description Eugene Shatokhin 2018-01-16 12:47:07 MSK
Upstream update to v.2.1-15.
Comment 1 Eugene Shatokhin 2018-01-16 12:48:07 MSK
The microcode for CPUs was updated to v2.1-15. This update includes Intel microcode version 20180108.

Build lists:


1. Please keep this update in testing for at least 2 weeks. There are reports like https://newsroom.intel.com/news/intel-security-issue-update-addressing-reboot-issues/ but it is still unclear if our users are affected.

2. If the loaded CPU microcode causes problems, one can disable it at boot time by adding 'dis_ucode_ldr' (without quotes) to the kernel options, somewhere before 'quiet'.
Comment 2 Vladimir Potapov 2018-01-17 10:19:07 MSK
The update is sent to expanded testing
Comment 3 Eugene Shatokhin 2018-01-23 12:33:09 MSK
Ubuntu users and maintainers have found a regression in this microcode update and, unlike Intel, provided some details:

"the only issue I'm seeing with my i7-7500U is the inability to *enter sleep* since I upgraded to intel-microcode 20180108. I initially described the problem as being unable to resume from sleep but upon closer inspection, the laptop simple never fully goes to sleep, the power LED remains on steady while it normally would turn off during sleep. My keyboard's LED does turn off though which is why I got mislead."

Comments from Ubuntu, from https://usn.ubuntu.com/usn/usn-3531-2/:
"At the request of Intel, we have reverted to the previous packaged microcode version, the 20170707 release."

So, let us wait till the next microcode update from Intel.
