I do not know. I do not have prior releases. I did not have the USB 3.0 hub prior to my reporting the problem. I reported this problem the first time I connected the 3.0 hub to my computer. The problem is not that the error message happens. The problem is that with linux after 3.2.0-38-generic, the error happens in a loop, forever. That has a severe impact on system performance. The important part of the previous sentence is 'in a loop'. Linux is distinct from Ubuntu. I can boot different kernels from Ubuntu 12.04.2 LTS at the grub prompt. I outlined the following to make the two cases distinct. I am sorry if I caused confusion by having two cases in one response. The good case: Boot Ubuntu 12.04 with linux 3.2.0-38 from grub ======================================================================== = = With the following combination, the looping and degraded performance = does NOT happen. = = > lsb_release -a = LSB Version: core-2.0-amd64:core-2.0-noarch:core- = 3.0-amd64:core-=3.0-noarch:core-3.1-amd64:core-3.1-noarch:core- = 3.2-amd64:core-3.2-noarch:core-4.0-amd64:core-4.0-noarch = Distributor ID: Ubuntu = Description: Ubuntu 12.04.2 LTS = Release: 12.04 = Codename: precise = = > uname -a = Linux P9X79 3.2.0-38-generic #61-Ubuntu SMP Tue Feb 19 12:18:21 UTC = 2013 x86_64 x86_64 x86_64 GNU/Linux = = The message appears one time for each failed address assignment.

I can boot the failing case and attempt to generate some information from there, if that will help. What can I do to help?
