Re: Boot problems with AMD64

    22:       9186   IO-APIC-level  libata, NVidia CK804
    23:      13705   IO-APIC-level  libata, eth0

These two could cause problems, I don't know what libata or nvidia is.
But if GNU Mach has support for your NIC and any of these two, it
might explain the sudden reboot.  Have you tried compiling a really
bare kernel with only say an IDE driver?

   I will try, but the most frequent result is still a reboot, so as a
   consequence it might take some time before I can get into gdb
   again.  Good to know that it's gdb by the way, since I know gdb. I
   was afraid that it might be something unique to mach.

To properly debug GNU Mach you will either have to use printf's in the
code, or hack it to support a serial debugger.  Or use GNU Mach 2.x,
which doesn't even compile.  For this you could have equally used nm
or somesuch instead of firing up gdb on the kernel image just to get
the function name where things died.
