From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

In order to make the kernel option persist, you will have to add the option to your bootloader config. Ubuntu probably uses grub, but in any case, I never can remember how to configure any of the bootloaders. Someone here can probably help out (or it'll be a quick search away, I'm sure).
Not the same distro, but on my system, the relevant file is located at
/etc/default/grub. Find the line that saysGRUB_CMDLINE_LINUX, uncomment it if necessary, and add your kernel parameter to it (mine hasGRUB_CMDLINE_LINUX="acpi_enforce_resources=lax", for historical reasons). Then rungrub-mkconfigwith appropriate arguments to regenerate your grub configuration.
