Subject: [REGRESSION] iwlfiwi with Intel Centrino N1000 won't work with power_save

Hi,
I got report from people that on Intel Centrino N1000 wifi won't work
after
updating to 3.17.8. I see in that release Fedora maints enabled
POWERCAP and
INTEL RAPL. We got working wifi only after disabling powersave via `iw
dev wlp2s0 set power_save off`.
How we can debug this?
lspci above.
