For what kernel version? And what's with all those netconsole error

Running kernel 4.4.4 is no good.. with the same setup as above but
only changing out vmlinuz and initrd.img, I run into a kernel panic.
"Kernel panic - not syncing: attempted to kill init!"
There was an error that I hadn't seen before about
"systemd-udevd: could not open builtin file
/lib/module

-lowlatency is Ubuntu's optional kernel config.
A stock Ubuntu kernel is CONFIG_PREEMPT_VOLUNTARY=y && CONFIG_HZ=250
The -lowlate
My deepest apologies.. I ran those commands on another computer (I'm
ssh tunnelling)...
here is the output of:
sudo mount -t usbfs none /proc/bus/usb
mount: mounting none on /proc/bus/usb failed: no such file or directory
cat /proc/bus/usb/devices: no such file or directory
sudo mount -t debug

What is "lowlatency"? Try 4.4.4 please, 4.2 is now old and obsolete :(

Regarding Kernel 4.2.0-30-lowlatency,
system-udevd is now giving me the outputs on boot:
seq 1106 '/devices/pci:00/:00:1a.0/usb5 killed (same for usb6)

I'm unable to use 8 of the 10 USB devices I have on a motherboard. Two
USB 3.0 ports work, and all of the devices, if plugged into a hub, can
be recognized and used if plugged through those 2 ports. However, the
other ports are completely unresponsive.
Thoughts/Ideas? The broken drivers are ehci-p
