I would look at the spannig tree state when the 2nd Linux server comes up.
I am not a Linux expert, but it sounds like it may be running spanning tree
instance that is causing the 3512's gig port to go into blocking mode. Does
the Linux server have more than one NIC? Just a thought.

Subject: trunking [7:1098]
We have a 3512 switching dot1q trunking to a 5500. The 3512 has a linux
server attached to the 3512 on a vlan. We have another linux server
attached
to the 5500 on the same vlan. The linux server on then 5500 works fine
until the 3512 linux server comes up and then we lose connectivity to 5500
linux server. We cannot ping either box when they are both connected. In a
quick fix we took off the trunking and put both gig port on the same vlan
and now it works fine. Any thoughts why trunking causes a problem.
Thanks
