raw)
I am trying to debug a kernel over a remote serial console. I get
Ignoring packet error ..
kgdb page suggests that it might be due to the speed mismatch. i tried
stty ispeed 9600 ospeed 9600 < /dev/ttyS0
on the development machine and have passed serial=0,9600n8 option and
gdbbaud=9600 via lilo to the debug kernel.
when i run
%stty speed
on the development machine it still reports 38400.
so i changed the gdbbaud and serial= values to 38400 on the test machine. even
this doesn't work.
any ideas?also on the development machine when i invoke
%gdb bzImage
gdb reports that bzImage is not an Executable file format and it is unable to
recognize the format. what is the problem?

ps: i have tried redirecting the kernel messages( without patching it with
kgdb) over the serial line and read it with minicom . that works fine.
please email as i am not subscribed.
