Finally I found the problem causing the sudden system reset : our setup :
P2020<====>PCI Bridge <=====> FPGA The reset occurs when we allocating skb and giving the Fpga dma addr of skb->data of this skb and when the FPGA tries to reach this address we are having a hardware reset. To fixed it we used GFP_DMA flag on skb allocations. If you can explain me few thinks I will be more then happy : 1) how come we managed to work in 2.6.32 kernel without this flag. 2) Ok gave you a bad dma address why reset the system without any warning.
