Hello,
I'm rebuilding my -Current box.
it's been reinstalled anew from the FreeBSD 4.0-19991229-CURRENT
snapshot.
I have on another box the full repository of FreeBSD (source, ports,
docs, ...) on another box, running 3.3-Stable and exporting the
repository via NFS.
I've tried to remake the world to the latest sources I had (got on 12/31
around 4PM GMT).
I can't get the "cvs co src" to finish properly : each time I launch
"cvs co src", the kernel crashes with page fault while in supervisor
mode : page not present (I don't have a serial console, so this is not
the full message). The instruction address for the faulting instruction
is always the same, in the "generic_bzero" (from a "nm" run on the
kernel).
The running process is always "cvs".
I have been able to check the sources out (one subdirectory after
another) and the machine has completed a full make world. I also run the
corresponding kernel.
with the new sources, there is the same problem with cvs : I have not
been able to check out the ports tree in one step (same error, in the
same routine).
The machine works fine : I have just completed a X11 3.3.5 build.
As I have got plenty of RAM, I'm not quite sure a full crash dump would
be usable.
Open to any suggestions
TfH
