Any help is most gratefully appreciated. Running X when doing major kernel hacking is not the best way to go. In theory, there's an interface in the kernel that could be used to prevent jumping into DDB when X is up, practically it's only used by pcvt, and i didn't even get it right there. :-( For all other questions, please refer to the kernel-debug.FAQ first. -- cheers, J"org joerg_wunsch@uriah.heep.sax.de -- http://www.sax.de/~joerg/ Never trust an operating system you don't have sources for. ;-)
