I can ping myself but can not ping gateway. could you give me some suggestion to debug it? Thank you I try the Linux 2.6.23 from Freescale, it has the same warning message. But the network works fine. so I think, this warning is OK. I did not get any interrupt and I find the interrupt number seems wrong. from mpc8313 manual, the interrupt number of TSEC2 should be 35, 36, 37. But in mpc8313erdb.dts file, it was assign to 32, 33 and 34. How to modify it? enet0: ... interrupts = < 37 0x8 36 0x8 35 0x8 > ---------------------------------------- in 2.6.23 mpc8313erdb.dts ethernet@24000 ... interrupts = <20 8 21 8 22 8 > ---------------------------------- what is the sequence, tx rx err or err rx tx? Thank you Ok, I got it. I modify interrupts to interrupts = <34 0x8 33 0x8 32 0x8> then I can ping. I will do more test later if I config both eth0 and eth1, I can not ping outside. but I can got the interrupt. also NFS still dose not work. I will continue next week. if I config both eth0 and eth1, I can not ping outside. but I can got the interrupt. also NFS still dose not work. I will continue next week. Here I got the exception output:
