Are there any know issues with jumbo packets?
Whenenver I set the MTU >1540 the NIC becomes unresponsive (can't even ping). In a previous life this h/w was windoze, and I did not have issues with jumbo packets. The MTU on the NIC can be set as high as 16110, though my switch can only handle 9K.
Any thoughts?
Thanks,

No known issues (yet). What is the network card model that gives you trouble?

Okay, after further testing, it looks like it's the gig cards that are misbehaving. I can bump down the MTU on my 3c509 without incident. If I change the MTU on the gig cards (up or down), those ports hang.
The gig cards in question are:
intel PRO/1000 MT Dual Port Server Adapter
intel PRO/1000 XT
The cards work without incident at the default MTU.
