USB won't work for that purpose. It requires far too much kernel support to be useful after a panic. The same goes for ethernet. There exists support for debugging over firewire - see dcons(4), and over old-fashioned serial ports. If you don't have either of those you are probably out of luck as far as remote debugging is concerned. -- <Insert your favourite quote here.> Erik Trulsson ertr1013@student.uu.se
