help building kernel after fresh install of V7

After installing a fresh simh V7 instance with 2 RP06's and a TU10, I tried building the kernel and running it. I got a panic. I didn't mess with the defaults, so I'm at a loss as to how the stock kernel is different from the one I built. I tried building as root, then sys, same effect. Here's what I did: nboot.ini contents:    set cpu 11/70    set cpu 2M    set cpu idle    set rp0 rp06    att rp0 rp06-0.disk    set rp1 rp06    att rp1 rp06-1.disk    boot rp0 pdp11 nboot.ini boot hp(0,0)unix (actually renamed hptmunix) mem = 2020544 CTRL-D login: root cd /usr/sys/conf make allsystems ... build stuff, no errors or warnings mv hptmunix / sync sync CTRL-E quit the sim pdp11 nboot.ini boot hp(0,0)hptmunix mem = 2021696 err on dev 0/0 bn=1 er=100000,4507 err on dev 0/0 bn=1 er=100000,4521 err on dev 0/0 ... etc. Am I doing something wrong or missing an important configuration step. I am just trying to rebuild the stock kernel before I try any reconfigurations. -- GPG Fingerprint: 68F4 B3BD 1730 555A 4462 7D45 3EAA 5B6D A982 BAAF
