Hello again, Frank, The problem here was before using kgdboe. It had to do with compiling the kernel. Yesterday, I've tried the "CentOS way" (instructions here: http://www.howtoforge.com/kernel_compilation_centos), and finally KGDB is booting. Regarding kgdboe, I thought this kernel supported it, but currently I can't confirm or dismiss that. Do you know if there is an easy way to clarify if my kernel supports kgdboe? Meanwhile, I'm also trying to connect through serial port.
