okme,

Unfortunately,  Ubuntu is not supported on the Inspiron 5415.

Edit grub as follows:

sudo gedit /etc/default/grub
Replace the following line:

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"
with

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash loglevel=3 vga=current pcie_aspm=off"
then SAVE & EXIT

sudo update-grub
sudo reboot
** Enjoy this could stop the flood messages.**

Hi, i have the same problem in my alienware 51mr2 ... the alienware m15 has linux support?
