One other thing to look at... > > dh_memory_start: c0000000 The failing kernel virtual addresses are 8015564b and 804b1210, so apparently you're running a kernel configured with a 2G/2G split? I'm not sure whether the crash utility even works with that configuration? Crash does support the old RHEL4 "hugemem" 4G/4G kernels, but I've never worked with a 2G/2G kernel. In any case, it may work by dumb luck -- to be sure, first try to run crash on the live system. Anyway, even though the dump header advertises a kernel configured with the traditional 3G/1G split (with kernel memory starting at c000000), that "dh_memory_start" field is not used by the crash utility.
