That strategy is helpful but for my team not as useful as you might think. We only have one production server in our lab. It is an x86 system with eight CPUs and 8 GiB of memory. Everything else in our lab is used for problem reproduction. So you never know exactly what state they're in. And most of the lab systems have only 1 GiB of memory which makes analyzing large dumps an exercise in thrashing the disks. Our little s390 system doesn't even have that much memory assigned to each LPAR. Also, we haven't been able to convince management to spend the money to upgrade our lab infrastructure. So we're limited to 100 Mbps ethernet between most of the systems. Heck, my desktop (dual core AMD 64 with 4 GiB of memory and two Western Digital Raptor SATA disks) is more powerful than almost all of my lab systems. As a consequence that is where I do all of my x86/x86_64 analysis. Dave, have you heard from rainer.bawidamann(a)de.ibm.com? He's leading an effort to create a cross-arch capable version of crash. Last I heard the current implementation only supports host=x86/target=ppc32.
