I'm experiencing the same problem mentioned above...

My OS is Ubuntu 10.04 and I'm using Adaptec 4 port NIC to connect to a 3550.

As mentioned above, I can see the ip address of the switch with "sh cdp neigh" but cannot ping in either direction..

Try booting your linux box on an older kernel version (ex. 2.6). This resolved my 802.1q issue.
