Does the switch reload? Do you have console access where you can be connected to the console and telnet in to see if you see anything on the console? If you can get in on the console, do a show log to see if you see anything questionable.
Just to make sure I have this right, you can start a telnet session, log in, but after that, your session hangs? Are you using any AAA (TACACSS or RADIUS) on the switch? Are you on the same VLAN as the management interface of the switch? Maybe some weird routing issue is cropping up as a telnet hang.?!
If you're fiddling with spanning tree, are you causing STP to re-compute? This could time out a telnet session, i.e. STP convergence will be 50 seconds by default, enough to time out a telnet sessions as the ports transitions from listening-learning-forwarding states.
