Router hangs - reboot clears

[chazk1]

Since putting in a new Cisco 4006 switch I have had problems with a Router which appears to hang and only comes back to life when powered off/on.

The Router is a 4500 with IOS 11.2
The switch is running 6.2(1)

On the local subnet I get no response when pinging the default gateway/ethernet address.

I have swapped out the data cable and the same thing happens.

The switch port stats show the following:

Port Status Channel Admin Ch
Mode Group Id
----- ---------- -------------------- ----- -----
3/1 connected auto silent 199 0

Port Align-Err FCS-Err Xmit-Err Rcv-Err UnderSize
----- ---------- ---------- ---------- ---------- ---------
3/1 - 0 0 0 0

Port Single-Col Multi-Coll Late-Coll Excess-Col Carri-Sen Runts Giants
----- ---------- ---------- ---------- ---------- --------- --------- ---------
3/1 76333 24093 0 20 0 0 0

The card on the Router is 10MB/Half Duplex and the switch port is set to the same.
Only this switch port has CDP enabled.
Portfast is NOT enabled.

Any ideas?
