With all kernel debugging options turned off, it will happen almost immediately and 100% of the time with the "ping-flood" test. Machine is nehalem (4 cores + HTT). So far I haven't been able to reproduce it with debugging turned on, but I'll gladly take any suggestions and do whatever I can to help fix it. --Jason
