kgdb core dumps

[Omer Faruk Sen]

Hi, I am trying to remote dump but I get the following erros. The 
kernel.debug is the file that I copied to my host system from target 
(remote). Why I am getting that error? Is there anything that I can do. What 
I have done is: 

1) boot system with a kernel (target)
2) set 0x80 in device.hints on target
3) Copy kernel.debug from target to host
4) CTRL-ALT-ESC on target
5) kgdb -r /dev/cuad0 /boot/kernel/kernel.debug on host and I get the 
following error. By the way with the src/ that comes with 6.0BETA-3 I can't 
get any output using kgdb -r /dev/cuad0 /boot/kernel/kernel.debug. I have 
cvsup'ed my source files yesterday but now I get these errors: 

root at balli# kgdb  -r /dev/cuad0 /boot/kernel/kernel.debug
