Locked Out

The popular employment-oriented social website LinkedIn seems to have a policy of not working with Linux based users. (Ubuntu mainly, although other users have reported difficultes)

I find that any search or edit request causes a freeze. What's been your experience?

More details are provided by a few industrious burrowers here

Update: a solution has been posted. Type in the following command:
sudo ifconfig eth0 mtu 1360
Arcane mumbo-jumbo it may be, but it does work!
