Download Kernel v8 with CONFIG_HZ=100
@minimec
I use the linaro toolchain to build the kernel(linaro 4.9.4 with Cortex A15 optimizations) and the Makefiles contain some specific linaro optimizations flags, that could have caused the errors you have encountered. Since v8 of the kernel you have to compile it with the 'make CONFIG_NO_ERROR_ON_MISMATCH=y' option or else you'll get an error at the end of compiling.
Also THX for your explanations regarding Kernel cross compilation. I will give it a new try. My idea was to enable zram maybe. That would again increase power consumption a little bit, but might help 'sfdroid' users.
Again... THX for your amazing work.

Do we have a kernel package of the default installation for fallback
purposes if something goes wrong after days, weeks?

Thank you.

A new flash will wipe your data. But you could tar your home directory and restore it afterwards...

News from the 100Hz front.
I had my phone over 8 hours in stand-by mode (idle) over night and lost 8% battery power.
I guess we can say that this is an improvement... I am pretty happy with these results.
Settings:
I was on 'msm-mpdecision' hotplug managment, slight undervolt, 'conservative' as governor.

I can confirm these observations, a great deal less power drain at idle. Still seeing the massive drain with screen on time, though. AIDA, top, lighthouse, nothing shows any crazy usage. I thought maybe it was doing something goofy with the GPU clock when web browsing and the like, so I stuck it at 100MHz for testing. Same results.
I don't really expect to get more than a day and a half total, but the screen on drain is very frustrating.
Still testing, still digging.
I do believe 100Hz timer is the right direction, though. Great work guys!

Do you guys use multirom at all? I had read that it wasn't the preferred method a while back, so I typically do a native install. Are there any side effects or drawbacks to using multirom for sailfish alongside other OS'es?
