[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] baqar79:
Many thanks for your hard work Tkkg1994! I've only just recently upgraded to Nougat, but I have been using your Marshmallow kernel ever since I first got root access on the phone.

I'm not quite sure if this is a bug (I was using v2.10.1), but I had an issue where running Geekbench4 would shutdown the phone, roughly after getting through the test 80% (Geekbench3 worked well though). You can't turn the phone back on from this state; but you can reactivate the phone by using the USB charger, where it will start charging, and from that point on you can't start your phone as normal.

After installing the latest Prime Kernel & SuperSU, I was able to complete the benchmark (I did only try it twice however).

I posted the issue over on the PRIME-kernel page, since I noticed someone there had exactly the same problem; so possibly it might be a bug?:

I did a very poor installation of your kernel however (what was I thinking installing the kernel after the initial setup of the Samsung OS :silly: ), so I had a lot of stability issues (mostly with Synapse crashing). But I noticed the performance was excellent (I only have KOTOR on the phone, but it seemed to have a higher framerate than on Marshmallow); and I got some crazy high Geekbench3 scores (2.6GHz BIG core, stock for LITTLE core on both kernels):

The one on the left is your Kernel, the one on the right is Prime. Very good results for nearly stock speeds!

I'm working on a fresh install to give Prime-kernel another go (since I just installed it over the top of your kernel), but it looks like the geekbench3 scores (just tested as of writing this) are still about the same as posted originally.

EDIT:I've since updated to the SuperKernel with the same installation. Performance improved (similar above), but I think the reason Prime-Kernel isn't as good as that it isn't scaling up to the selected maximum clockrate I set within Synapse.

Overall seems noticeably more stable than before, even though I installed it over the top of Prime-Kernel. I use my phone for video mostly and...it's probably to early to say, I think it might be a battery calibration issue...but even if it was down to the battery callibration being off, I was very much enjoying a never before seen 10mins/1% of video playback...I think it's too good to be true, so take it with a grain of salt (really want it to be real..16+ hours of video playback for the S7 Flat on one charge would be nice.....)

Synapse seems to be crashing a whole lot less now, but I chose a different busybox to install (First time I installed BusyBox by Stephen from the Android store, this time it was BusyBox by meefik which is free).

GeekBench 4 though performs the same crash on the same installation that worked fine with the Prime Kernel. It gets to about 80% and then once I see the "HDR test" the phone switches off and has to be plugged in to be turned on again.

Furthermore, I usually run a disk repair in TWRP after a crash like that, and for some reason there is a problem repairing /system with an error pointing to /dev/block/sda14 . To fix this, I seem to have to browse to that folder within TWRP, and then the /system partition can be repaired.

EDIT2: Looks like this is actually a well known problem with GeekBench4 (just not well known to me): https://xdaforums.com/showpost.php?p=74880350&postcount=304 so ummm...carry on? :)
