Re: Ultra 5 SSH/Ethernet Lockup

[Patrick Morris <trick@adonis.net>]

Have you checked the duplex settings on the card?  I saw similar things 
with my Ultra 5's connecting to Cisco switches because autonegotiation 
wasn't working properly, and the U5's were setting themselves to 
half-duplex.  If I pushed enough traffic across the line when the 
duplexes didn't match, they'd lock up.  I don't know if it's a problem 
with just the build-in ethernet or with U5's in general.

If you've got the ethtool package installed (apt-get install ethtool), 
try running "ethtool eth0" and check to see if everything looks right.  
I had to use ethtool to turn off autonegotiation and force full duplex 
at boot.
