--bcaec51ba00f469f9e04db5ce13e Content-Type: text/plain; charset=ISO-8859-1 Attached is my work on ppc64 kernel dumps, based on my ppc32 dump code (stolen from booke). There is one problem that I see, but I can't figure out how to solve, which is that on my machine at least, after some number of chunks dumped, the ATA transfer times out, failing the dump. I think it wedges the DMA controller, but I'm not certain. Maybe Nathan, or someone else, can shed some light on it. - Justin --bcaec51ba00f469f9e04db5ce13e Content-Type: application/octet-stream; name="dump_oea64.diff" Content-Disposition: attachment;
