Any attempt to dump to an SD card leads to a hang with no diagnostic. Maybe that depends on a controller? >From reading the code, it seems that mmcsd_dump calls into the regular write path and I could not find any special handling for the post-crash environment (like polling instead of interrupts, etc). Also, I see that mmc_da.c does not provide a dump method at the moment. -- Andriy Gapon
