EDIT: Made a fresh install with Gnome today's image. Didn't get any issues.

There is only one missing piece here : Nautilus 3.18.x

Perhaps because this?

[dino99]

nautilus 3.18-5 from gnome3 ppa here
wonder why the desktop team is introducing a bigger delta with the gnome dev trend The little design problems are very harmless

[P-I H]

Compiled RC3.
Takes a little longer to boot
RC2

p-i@pi-GA-990FXA-UD3-xenial:~$ systemd-analyze
Startup finished in 4.808s (kernel) + 9.459s (userspace) = 14.267s

RC3

p-i@pi-GA-990FXA-UD3-xenial:~$ systemd-analyze
Startup finished in 8.996s (kernel) + 9.596s (userspace) = 18.593s

Unigine Valley has about the same result as on RC2 with POWERPLAY=y and a Radeon R9 380.

Did you know, you can copy the old config file and do "make oldconfig", this will only prompt you for any new config items.

Did you know, you can copy the old config file and do "make oldconfig", this will only prompt you for any new config items.

I suspect that most people that compile their own mainline rc series kernels would know that.

For my part of it, I often steal the Ubuntu kernel configuration just keep synchronized the Ubuntu mainline rc kernels. I don't do it every time, but have noticed the Ubuntu kernel configuration often changes significantly, including changes to old settings. On these rc threads, we have found a few issues with the Ubuntu kernel configurations, that have resulted in bug reports and/or escalation to the kernel team via their IRC channel.

Myself, I have never ever used "make oldconfig", I Just compile telling it to use defaults wherever there is some kernel configuration decision needed, which can be particularly useful when doing a kernel bisection. I.E. my process for rc3 was:

cp /boot/config-4.5.0-040500rc3-generic .config-4.5.0-040500rc3-generic
cp .config .config-4.5-rc2-doug
cp .config-4.5.0-040500rc3-generic .config
scripts/config --disable DEBUG_INFO   <<< Otherwise the kernel is giant sized and compile takes twice as long
scripts/config --disable CC_STACKPROTECTOR_STRONG   <<< Because I compile on a 14.04 server, with an older version of the c compiler
cp .config .config-4.5-rc3-doug
git checkout master
git pull
git checkout -b k45rc3_stock v4.5-rc3
time make -j9 olddefconfig bindeb-pkg LOCALVERSION=-stock
sudo dpkg -i ../linux-headers-4.5.0-rc3-stock_4.5.0-rc3-stock-157_amd64.deb
sudo dpkg -i ../linux-image-4.5.0-rc3-stock_4.5.0-rc3-stock-157_amd64.deb
diff .config .config-4.5-rc3-doug  <<< changes should be minimal. They are.
cp .config .config-4.5-rc3-doug   <<< Save it anyhow

Some differences between kernel 4.5 and 4.4

systemd-analyze 4.5
Startup finished in 8.951s (kernel) + 5.968s (userspace) = 14.920s

systemd-analyze kernel 4.4
Startup finished in 4.769s (kernel) + 7.951s (userspace) = 12.720s

Unigine Valley benchmark kernel 4.4
FPS: 9.7 Score: 407

Unigine Valley benchmark kernel 4.5 with powerplay enabled
FPS: 43.1 Score: 1803

Kernel 4.5-rc4 is available. Myself, I'll have to stay with -rc3 for awhile, as I 'm in the middle of some tests.
