[Bug 1489622] Re: 15.10 20150826 snapshot -- MacBookPro3, 1 has high load (and temperature) despite low CPU and low IO
On one particular boot with the external power connected, there were
only 1176 interrupts for this event a few minutes after boot. It was
stable at 1176. Upon disconnecting external power, it started its rapid
cycling. Reconnecting the external power source did not solve the
problem.
On another boot when running on battery, the same thing occurred upon
connecting the external power source.
When in such a stable state for the interrupts, behavior matches them
being disabled (which one would likely expect), with load averaging
around 1.15-1.25 (compared to 1.65-1.95 when the interrupts are
constantly firing).
So we probably need a quirk to just ignore this power-state-change GPE
and still need to figure out the rest of the issue.

Title:
15.10 20150826 snapshot -- MacBookPro3,1 has high load (and
temperature) despite low CPU and low IO
Status in linux package in Ubuntu:
Confirmed
Bug description:
I just put the 20150826 15.10 snapshot onto my MacBookPro3,1. I
blacklisted nouveau due to
https://bugs.freedesktop.org/show_bug.cgi?id=91779 and updated systemd
to start in text mode instead of launching X11.
After booting into this configuration and letting the system idle, it
is consuming only about 3% CPU but has a load average of 1.5
$ uptime
14:23:00 up 11 min, 3 users, load average: 1.65, 1.55, 0.95
$ vmstat 1
