I used the config, make depend, make, make install procedure. make depend took about 20 min, make took about 1 hr 20 min. I did a soft reboot: shutdown -h now, hit any key to reboot, hit space at count down, booted with command "boot -v". As before the system proceeded to the "isa0:" line and then locked up. At this point I tried Ctrl-Alt-Esc to enter the debugger, but nothing happened. It seems to be too locked up for the debugger. Maybe I could try hitting Ctrl-Alt-Esc before it gets to the "isa0:" line and stepping through the code up to the error? Any suggestions? Cla.
