Hi.

Has anyone else experienced what feels like lockups when connecting to the 
TS7500/TS7550 boards using telnet?

This is running Debian on the boards and does not affect TS7250.  

While typing away, every few minutes (but not predictably or consistently) it 
suddenly seems to go dead, only to carry on where you left off after around 30 
seconds or so.  It is not related to filesystem access as far as I can tell.  I 
wrote a program to usleep and produce a histogram of delays, and this shows it 
is not a system wide lockup - in addition the watchdog does not go off.

If you have another telnet session to the same board, that will experience 
lockups at different times to the first one. 

All the systems (TS7250 and TS7550) are on the local subnet. 

It feels like a network problem, and I have some evidence that characters I 
type are being received but not echoed.  If I type a command that has an effect 
on the LEDs, that is actioned even though I cannot see the keystrokes I enter.

I've never seen a problem exactly like this and would welcome any suggestions 
for solution or investigation.

Martin
