I believe the problem lies with the Intel iwlwifi driver (iwlagn module in our case) and it only started affecting me when I upgraded from Ubuntu 10.10 to 11.04 - sadly I don’t know what kernel version 10.10 was using but this is important because iwlagn is now a standard kernel module. I have exactly the same problem with my 5100 and it affected me on Ubuntu 11.04 too.
