I also had these connection getting stuck randomly problem, they appeard when transfering much data using samba server and a windows client with a gigabit connection.
I applied the patch from http://marc.theaimsgroup.com/?l=linux-kernel&m=116060287918559&w=2 to the sky2 v1.4 driver from ubuntu 2.6.15 kernel source and it seems to work, the lockups are gone.
