I'm trying to debug panic()s in one of my drivers (I can compile it only as module now), but I can't find a way to get address where it was loaded by kldload. I can't run kldstat (as recommended by developers' handbook, 17.6) because it panic()s during kldloading (after LOR of ZONE_LOCKs after malloc(0) somewhere in device_attach of my driver). Can I get this address inside kdb? Another question, what is correct behavior of malloc(0, M_DEVBUF, M_NOWAIT | M_ZERO)? Yuriy Tsibizov
