Hello. I never used brd on Trusty, all my previous experience with it was on Debian/Centos (they both have brd as 'm').
I've checked - even precise have it as 'y' - this make Ubuntu very different compare to all other distributions. Main problem is that 'y' makes brd 'OS only' because it size fixed. And it makes impossible to free used by ramdisk memory by unloading module. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1593293 Title: brd module compiled as built-in Status in linux package in Ubuntu: Triaged Bug description: Block RAM disk module (brd, CONFIG_BLK_DEV_RAM) compiled as 'y', that means it is 'built-in' and can not be unloaded or loaded with different parameters.
