Forgot to mention, it's 100% reproducible, and very easily. All that = needs to be done is have an interface (eg ib0) be in IPoIB mode with an IP = assigned. (eg 10.10.100.1) When that interface is pinged from another host (eg "ping 10.10.100.1") = the kernel panic immediately happens. Every time. ;) + Justin -- "My grandfather once told me that there are two kinds of people: those who work and those who take the credit.
