That makes it slightly less likely that you'll be able to learn anything useful. If you can make it croak, or if it does it all the time, you'll at least be able to see the last syslog message if you were watching tty12 when it happens. > Happens w and w/o X, in single-user mode, multiuser mode, with various > modules loaded or not. What a pain. (this is the point where the "OPC" > user says "linux sucks" :) Yeah. > How do I put it on tty12? Alt-f12, or ctrl-alt-f12. This only works after syslog (or whatever) has opened tty12. Note that if the kernel has already wedged, you probably won't be able to switch virtual terminals. As a result, you're probably best off either: directing it to a file and hoping that the file gets written before the hang, or leaving the system on tty12 and hoping it hangs without user intervention (such as running some particularly naughty piece of code). If you're going to do the latter, you probably want to turn off automatic console blanking (setterm -blank 0).
