Ulp!! I just had my first panic in a year, and remembered why I didn't
want to use modules too much, because when I tried to revert, the old
kernel didn't like the new modules (procfs, it seems).
Anyhow, I handcopied the panic message, here it is, I'd extremely
appreiciate any help in getting a new kernel to boot. I finally got my
old kernel up by not loading procfs.ko ... Oh, yeah, I booted this 3
times with the same message, it's not a random occurrence. Since I
handcopied this, and my printing is in block letters, I don't
differentiate between upper and lower case, so don't read anything into
that.

This is my first kernel since the nexus stuff was brought in, and I had
to edit my config file to get it to stop issuing me errors ... here's my
config, I hope this helps:
