ChaosBSD Is A New BSD For "Broken Drivers, Half-Working Hardware, Vendor Trash" Test Bed - Phoronix

A new BSD on the block is ChaosBSD that intends to serve as a testing distribution for unfinished and broken drivers not suitable for upstreaming to FreeBSD proper.

ChaosBSD is a downstream fork of FreeBSD that is self-described as:

        "A Driver Proving Ground  

    ChaosBSD is a fork of FreeBSD. It exists because upstream cannot, and should not, accept broken drivers, half-working hardware, vendor trash, or speculative hacks.  

    We can."
