SKB corruption on heavy traffic

Hello Community!

	We are developing a MPC8247 based telecom board (512MB), using
linux 2.4 with some proprietary changes on IP stack and we are facing
some problems when we have heavy traffic on our Ethernet interfaces...
Namely:

		- When sending a ping flood we have skb corruption after
some variable time (looks like memory problems). Resuming what seems to
be happening: after release (dealloc) of the skb, the kernel tries to
access it again. To verify this we have implemented a list of "to be
freed" skb to have a delay between the time they are freed by the stack
and the actual dealloc. In this delay we are able to verify that the skb
is changed.  
		- We have reports of DMA transfers not completed in
heavy traffic.
		- After a while, and skb corrupted messages appearing in
the console, we start to have a scrambled characters. So, after some
seconds we don't understand what is written. This problem solves after
the crash or reboot. Which means that uart also seems to crack in heavy
load or at least some.


Below are some of our traces that show our problem... Someone has some
hints of what could be leading to this?? HHHHEEEEEELLLPP!!!!


Huge Thanks! 
Filipe.
