I have had installed the linux-image-2.6.26-1-686 package but my PC Box reboot automatically often. So I install linux-source-2.6.26 package and compiled it with CONFIG_CRASH_DUMP=y option, and installed it. I did the following: [code] $ sudo aptitude install linux-source-2.6.26 zlib-bin zlib1g zlib1g-dev zlibc $ cd /usr/src/ $ sudo -E tar xvfj linux-source-2.6.26.tar.bz2 $ cd linux-source-2.6.26/ Copy the /boot/config-2.6.26-1-686 to the /usr/src/linux-source-2.6.26 as .config and edit the line to be: CONFIG_CRASH_DUMP=y $ sudo -E make oldconfig $ sudo -E make CONFIG_DEBUG_SECTION_MISMATCH=y $ sudo -E make-kpkg -initrd kernel_image I want to install kexec-tools for crash dump analysis. Is it enough or must I install more packages, say: crash, crash-whitepaper, watchdog? How can I use these tools for crash dump analysis? -- Regards, Paul <http://sourceforge.net/projects/lptinterface/> <http://savannah.nongnu.org/projects/lpt-interface/> <http://csanyi-pal.info> -- To UNSUBSCRIBE, email to debian-user-requ...@lists.debian.org with a subject of "unsubscribe".
