Kexec based crash dump approach exports a device interface to read/save the crash dump in elf core file format and user shall be able to analyze the dumps using gdb. Initial set of patches were posted by Hari on LKML for review. Please have a look at following thread. http://marc.theaimsgroup.com/?l=linux-kernel&m=109274443023485&w=2 Very soon Hari is going to post the final set of patches to be included in -mm tree.
