Now, it's safe to call the fwohci interrupt(polling) routine while ddb/gdb is active. After this change, a dcons connnection over FireWire can survive bus resets even in kernel debugger. This means that it is not too late to plug a FireWire cable after a panic to investigate the problem. Actually there is a small window(between a jump to kernel from loader and initialization of dcons_crom) in which no one can take care of a bus reset. Except that window, firewire console should keep working from loader to reboot even with a panic and a bus reset. (as far as you enable LOADER_FIREWIRE_SUPPORT) Revision Changes Path 1.8 +14 -0 src/sys/dev/dcons/dcons_crom.c 1.15 +1 -0 src/sys/dev/dcons/dcons_os.c 1.3 +4 -0 src/sys/dev/dcons/dcons_os.h
