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'

Sorry, I do not have the kernel debug due to the kernel is not running with any
debug options. I will compile them in as soon as possible. Or is there another file
I'm not aware of?


No, you have to compile with DEBUG=-g to get a kernel.debug.  If you can reproduce
the fault and get an updated instruction pointer address, you will want to do a
gdb list command on that address.

:>This is quite helpful.  Do you have the kernel.debug from this
:>kernel still?  If so, run 'gdb -k kernel.debug' and then type
:>'l *0xc01b29db' to find the file and line that it panic'd at.
