Installed it about a month ago. Been doing all the updates. (I am surprised there are so many updates to this kernel, seems to be one or two a week.). I had one today. I am now at = 2.6.37-2.dmz.1-liquorix-amd64.
Everything is running fine. Haven't noticed any appreciable changes since the first Liquorix kernel install. I do like it, as its the only kernel, that lets this computer (see signature) use suspend/hibernate. Maybe your having a video driver problem? I installed the Nvidia 195 drivers from synaptic before the Liquorix, and every new Liquorix update has automatically compiled the Nvidia driver with me having to do nothing. It just boots back smoothly into the new kernel with Nvidia and compiz working smoothly.
Perhaps checking out the Liquorix forum would help?http://techpatterns.com/forums/forum-34.html
