Description of problem: When run /mnt/tests/kernel/networking/ndnc tests, This will configure netdump to dump across the network. Then manually initiate a Alt+SysRq+C to crash the system, kernel panic appears. Version-Release number of selected component (if applicable): 2.6.9-96.ELsmp How reproducible: always Steps to Reproduce: 1.run /mnt/tests/kernel/networking/ndnc tests 2.run "echo 1 > /proc/sys/kernel/sysrq" and "echo c > /proc/sysrq-trigger" to crash the system. Actual results: Code: Bad EIP value.
