Linux version 3.19.0-28-generic (buildd@lgw01-21) (gcc version 4.8.2 (Ubuntu 4.8.2-19ubuntu1) ) #30~14.04.1-Ubuntu SMP Tue Sep 1 09:32:55 UTC 2015

I was able to get the latest kernel 3.19.0-28-generic and it seems to be working fine. Not sure if it was the problem, but unsupported updates was checked by default from DELL which seems odd. I unchecked that and checked pre-supported updates and used the following commands to upgrade to the latest kernel:

sudo apt-get install --install-recommends linux-generic-lts-vivid xserver-xorg-core-lts-vivid xserver-xorg-lts-vivid xserver-xorg-video-all-lts-vivid xserver-xorg-input-all-lts-vivid libwayland-egl1-mesa-lts-vivid

I was able to resolve my problem.  I replaced the hard drive to make sure I had all of the files on it in case I ever needed any of them.  I used Unetbootin with 64-bit Ubuntu 14.04.03, and did a clean install.  Everything but the trackpad worked.  To make the trackpad work:  

sudo vi /etc/modprobe.d/blacklist.conf

add this line to the end of the file:

blacklist i2c-hid

save, close, reboot

Everything works now.

I have also been having the same problem.  My fix was to re-download a fresh version of Ubuntu directly from the website.  Although in doing this I have encountered 2 more errors.... 1) If I try to install Ubuntu in UEFI boot mode - my touchpad doesn't work. 2) If I install in legacy bios mode, the touchpad works but the laptop never completely shuts down, or goes to sleep correctly- very strange since in UEFI mode the laptop does shut down and goes to sleep properly.  I haven been searching for fixes but haven't seen anything yet.  I have also tried the newest version of Ubuntu to clarify if its a software or hardware issue. It appears to be hardward issue on Dell's side.

This issue was solved by doing the following. 

Add initcall_blacklist=dw_i2c_init_driver to the kernel command line. This works for me on kernel 4.15.0+.

For anyone else who'll find this answer. You can do it by editing /etc/default/grub:

Run in the terminal: sudo -H gedit /etc/default/grub.

(if you don't have gedit installed use your favorite text editor or
"sudo apt install gedit" without quotes)

Append blacklist string to the GRUB_CMDLINE_LINUX_DEFAULT: GRUB_CMDLINE_LINUX_DEFAULT="quiet initcall_blacklist=dw_i2c_init_driver".

Save the file, close the editor.

Run in the terminal: sudo update-grub.

Reboot and test!

This kernel panic also happens on the R7 as well, it's to do with the designware modules not being loaded.

These are my specs for this rig.
Alienware Aurora R5
Nvidia GTX 1070/8GBvram
8GB ram
i7 Intel core processor(8core)"Skylake"

Thanks, it solved the same issue for me as well on Ubuntu Budgie 20.10 on Aurora R5. After all these years it remains an issue.
