boot up hangs after catalyst update

[forumhero]

I was able to figure it out. something weird about the 14.4 driver on my system. Ended up installing 14.6 beta which wanted me to install dh-modaliases execstack debhelper. now the system boots up fine and all 8 GPUs recognized by oclHC 1.21 and OS. just need to remember to use the --force switch
