To prevent this reset, add "pcie_aspm=off" to the kernel command line parameters by doing either of the following actions:
- Using the Grubby command line tool: /sbin/grubby --args=pcie_aspm=off --update-kernel=ALL
- Using your text editor to edit /boot/grub/grub.conf (i.e. vim /boot/grub/grub.conf) so you can add the required parameters to at least the first (default) item in the menu
Example:
default=0
timeout=5
splashimage=(hd0,0)/grub/splash.xpm.gz

Reboot the system to load the kernel with the new parameters.
