I just finished updating my system to the june 02 snapshot of NetBSD-amiga.
Everything worked fine until I tried the new generic kernel.  When I
booted in single user mode, it would tell me the filesystem was not clean
and I shoult run fsck to fix it.  When I ran fsck it ran through the root
fine, but when it tried my usr partition, I got this:

vm_fault(f6000, 3004000, 3, 0) ->1
                                  vm_fault(f6000, 3004000, 3, 0) ->1
vm_fault(f6000, 3004000, 3, 0) ->1
                                  vm_fault(f6000, 3004000, 3, 0) ->1
vm_fault(f6000, 3004000, 3, 0) ->1
                                  vm_fault(f6000, 3004000, 3, 0) ->1
vm_fault(f6000, 3004000, 3, 0) ->1
                                  vm_fault(f6000, 3004000, 3, 0) ->1
vm_fault(f6000, 3004000, 3, 0) ->1
                                  vm_fault(f6000, 3004000, 3, 0) ->1
vm_fault(f6000, 3004000, 3, 0) ->1
                                  vm_fault(f6000, 3004000, 3, 0) ->1
vm_fault(f6000, 3004000, 3, 0) ->1
                                  vm_fault(f6000, 3004000, 3, 0) ->1
vm_fault(f6000, 3004000, 3, 0) ->1
                                  vm_fault(f6000, 3004000, 3, 0) ->1
vm_fault(f6000, 3004000, 3, 0) ->1
                                  trap type 1, code a66d, v=ffffffff

And then it froze up completely.

I tried re-installing it and not running fsck, but it would still freeze up
at some point with the same results.

Is this because I have to make a new filesystem?  and if so how am I
supposed to do that without wiping out everything?
