Blacklisting the samsung-laptop module in UEFI mode fixes the related but separate issue of the kernel crashing on bootup. The root cause of the bricking was that Samsung's firmware had an undocumented requirement of 5KB of free UEFI variable space to be able to start up. The kernel crash would cause a log dump, which could cause the variable store to be filled beyond this limit. (Matthew Garrett provided a more detailed report in his blog last year: http://mjg59.dreamwidth.org/25091.html )
Handling of UEFI variables was changed in the kernel (in Ubuntu 13.10 and newer), and Samsung supposedly made fixes to their firmware, so the bricking issue is fixed. As far as this bug is concerned, the installation procedure is to update your firmware to the newest version and then install Ubuntu as usual. Driver support for particular laptop models should probably be addressed in separate bug reports.
