Also includes the corresponding System.map file, the modules built by the packager, and scripts that try to ensure that the system is not left in an unbootable state after an update. . Supports Generic processors. . Geared toward desktop and server systems. . You likely do not want to install this package directly. Instead, install the linux-generic meta-package, which will ensure that upgrades work correctly, and that supporting packages are also installed.

I have several of these machines & all have been happy on 3.16.0-34. Today I did an install & the post-install updates picked up 3.16.0-36 & now it won't boot successfully -- black screen, backlight still lit, no response to any keyboard input. I downloaded & installed the current mainline upstream kernel & it works fine.
