No workaround. kern/118093: firewire bus reset hogs CPU, causing data to be lost Firewire driver must be locking out other drivers (e.g. ethernet) when it shouldn't. I still think it is a locking/mutex type problem. Why does the firewire driver need to lock out Ethernet? The new rs-232 driver in 8.0 didn't fix this. Workaround: change printfs to log(9) so that it doesn't print to console.
