Minutes after I reported that I had no reboots for 2 days, had upgraded, and compiled a new kernel with: options DDB options DDB_UNATTENDED .... and reboot! That is the latest 3.1-Stable (03/05/99). Unfortunately I had only just compiled in: config kernel root on da0 dumps on da0 and had not the chance to boot the new kernel. Now what? I do not know enough about this to do it alone.
