I will try to do so, but I understand reading the documentation (http://user-mode-linux.sourceforge.net/old/UserModeLinux-HOWTO-11.html#debugging) that in order to get a stack trace I need to compile the UML kernel with CONFIG_DEBUGSYM and CONFIG_PT_PROXY. However, I haven't found these options in the 'UML-specific options' submenu of 'make menuconfig ARCH=um'. As a matter of fact a 'grep -R CONFIG_DEBUGSYM *' in the kernel tree source (vanilla 2.6.22.4) shown no match (except one in UserModeLinux-HOWTO.txt) and this make thing that maybe I've read an obsolete documentation. It's something wrong in what I'm doing? Is there any other document explaining how to debug a UML kernel? Or just I have to edit the .config and add a 'CONFIG_DEBUGSYM=y' and 'CONFIG_PT_PROXY=y' to the end?
