Comment 250 for bug 1040557

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.
