Hi John, I'm having this same problem and I would love to get you a kernel.debug core however I've discovered after building the debugging kernel, the system literally panics during the kernel install. Do you have any suggestions to get the debugging kernel installed successfully? The last thing it tries to install prior to the panic is 'gx' John Baldwin wrote: > On 22-Aug-2003 Hartmann, O. wrote: > >>On Thu, 21 Aug 2003, John Baldwin wrote: >> >>Sorry, I do not have the kernel debug due to the kernel is not running with any >>debug options.
