Kernel 4.4 RC (Release Candidate) series

[Doug S]

Kernel 4.4 RC1 does not build for me. It seems the Ubunutu PPA version has the same issue. My error message:

Late to the party but Phoronix had an article on this

He's also hosting a patched kernel linked in the same article <-- haven't tried myself

Decided to take this route, But no headers so it will break Nvidia of course.
I also noticed that he has one with the AMD GPU, might give that one a go a little later today.
Can't wait to see this one bench out.
So far so Good dose not seem to generate a lot of heat on my Nvidia card, And CPU Power consumption is just slightly higher with clock speed @2600Ghz

Yee Haa! Now to start Benching.

I been using Phoronix's AMD GPU 4.3 kernel with re-clocking support for some days in Xenial. It supports re-clocking of tonga and fiji graphic cards. Unigen Heaven with a Radeon R9 380 without re-clocking runs with 7.2 FPS and with re-clocking 34.7 FPS.

Kernel 4.4-rc2 is available (but not on the Ubuntu PPA yet).
In terms of ability to compile, it has the same issue as rc1.

As some others mentioned above, it can be made to compile via kernel config file changes only, instead of the patch method I used for rc1.
The kernel config file differences:

doug@s15:/media/sda/home/doug/temp-k-git/linux$ diff .config-4.4-rc1 .config-4.4-rc2
6882,6889c6882
< CONFIG_LUSTRE_FS=m
< CONFIG_LUSTRE_OBD_MAX_IOCTL_BUFFER=8192
< # CONFIG_LUSTRE_DEBUG_EXPENSIVE_CHECK is not set
< CONFIG_LUSTRE_LLITE_LLOOP=m
< CONFIG_LNET=m
< CONFIG_LNET_MAX_PAYLOAD=1048576
< CONFIG_LNET_SELFTEST=m
< CONFIG_LNET_XPRT_IB=m
---
> # CONFIG_LUSTRE_FS is not set

Edit: actually, it appeared in the ubuntu PPA (along with the compile issues) while I was writing this post.

[Doug S]

There are now completed builds in a special directory on the Ubuntu PPA.
I have some issues with my test server at the moment, and am unable to try the Ubuntu version of the 4.4-rc2 kernel, but I have been running my compile of 4.4-rc2 for a day or two now.

Thanks Doug S
Everything seems to be fine.
Got Nvidia installed, Bonus!
I used this PPA ppa:graphics-drivers/ppa

Doug S I used the build in the ubuntu ppa and it loaded once, ran well with no issues. I shut down and tried to restart and it crashed with a kernel panic. I restarted with a previous kernel - no issues. I tried restart to the 4.4 kernel and again got the kernel panic. I restarted and purged the 4.4 kernel, rebooted to 4.3 kernel. I again installed the 4.4 kernel, rebooted. 4.4 came up and ran with no issues. Rebooted and got the kernel panic. Where to start looking for a solution? Using Xenial Gnome 16.04

The only thing I know to do in your situation is to bisect the kernel to identify the exact commit the caused the issue, and then report it (myself, I typically bypass launchpad and report it directly upstream). Bisecting the kernel can take a lot of time (I am in the middle of a bisection right now), and you need to be comfortable compiling the kernel. Since we are still relatively early in the RC series, you could also just wait and try rc3, rc4 ... to see if your issue gets resolved by someone else. The kernel should be fairly stable by about rc6.

Someone else might have some other suggestions.
