Not sure if this is two question, but I wanted to start with both here in case they are related. I use a Linux PXE and grub for dos boot in various ways. I have used the same file system adding a few scripts here and there but mostly updating the kernel for new hardware. Starting with kernel 3.12.xxx and the latest 3.18 rc4 main line I am getting "oom_adj" deprecated and some wait_for_sysfs errors. My Linux skill level is somewhat basic out of ignorance mostly. I have goggled and learned a lot, so just because I use a term it does not mean I know what I am saying :-)
Background:
I started by remastering P.I.N.G from windowsdream. http://www.windowsdream.com/ping.html This is a cool ISO that will backup and restore hard drive images to a share. It's basically a big Pearl script that uses Linux commands to create shares, save partition, clear and make them back. So I started with that and made a intrd.gz file system. So I imagine a lot of my issues could be out of date lib's, my udev rules need to be updated, or my kernel make file (.config) is wrong. Also, sometimes, not always, my mouse USB will cycle though disconnects/re-connects. It seems to very from boot to boot. This boot may do it and the next boot will not. I will attache some screen shots and my .config file. BTW, P.I.N.G was based on Linux From Scratch (LFS).
Questions:
The open ended question is how to fix it?
Are the following questions related?
Is there setting in the .config to switch from oom_adj to oom_score_adj?
Is the /proc/2000 a lib issue?
Is the waiting_for_sysfs udev rules issues?
For the USB disconnecting/re-connecting, I read somewhere that Intel question something about some timing and some cheaper hardware may have pushed the spec a little. I can not find it any more. I did find something in the .config about using uHCI, but I saw somewhere about xHCI. I assume it has something to do with USB 2.0 vs USB 3.0, but I am not sure. Also, is this USB 1? 
Any thoughts?
Looks like there are too many lines for the .config, I don't see how to attach it. If anyone wants to see it, let me know either how to post it or send it to them.
