[Linux-Biella] scanner e 2.6.2rc1

[Paul TT]

qualcuno di voi usa scanner usb?!?!?
perche' a me, col 2.6 suddetto funziona tutto quanto perfettamente, ma 
quando unpluggo lo scanner dalla porta usb, mi si apre l'xmon debugger e 
mi insulta cosi':

presumo che sotto architettura intel sia piu' cattivo ed inchiodi la 
macchina, probably.
sono strabiliato ogni volta che uso l'xmon, e' un debugger del kernel 
che entra in azione in questi casi, e spesso chiudendone il prompt, 
passa all'istruzione successiva senza colpo ferire al sistema.
ah, che io sappia, esiste solo per ppc ;-)))
