The question about the linux Exception during the GETH test on MPC8360?

[郭劲]

HI,friends,

I tested the GETH on MPC8360 by "iperf", after several times test, the linux is
dead, please see follow information. Then I slow down the core frequency from
667MHZ to 533MHZ, the test is OK, could you tell me where has the problem?
Thanks.
