Bug Description
I have a weeks old Lenovo T460s running Ubuntu 16.04. After seeing
MCEs for due to temperature, I was advised to try the upcoming HWE-Y
kernel.
I installed linux-image-
canonical-
When I returned to my machine in the morning I found it had hard
locked up over night, it was very hot and all the fans were going at
full speed.
With the 4.4 kernel, I got messages like the following:
Sep 17 22:45:13 malefic kernel: [213000.178417] CPU2: Core temperature above threshold, cpu clock throttled (total events = 9521)
With 4.8, it increased to:
Sep 20 17:14:13 malefic kernel: [24571.915198] CPU2: Core temperature above threshold, cpu clock throttled (total events = 42953)
(Although there's a fair bit of variation).
I also noticed that thermald was spewing a lot of error messages to
syslog:

The thermald spew went away and the number of 'temperature above
threshold' events went down once I downgraded back to 4.4.
Changed in thermald (Ubuntu): | |
status: | New → Incomplete |
importance: | Undecided → Medium |
Basically sysfs writes are failing with 4.8 kernel, so all those errors in http:// paste.ubuntu. com/23207813/.
