Hi, I have a question about kexec and kdb. Please advice or point me to the right mailing list that can answer this. I have a linux 2.6.20 kernel (patched with kdb patches) on i686 system. I have setup a crash kernel using "kexec -p" command which is working very well. I tested this by triggering a crash by using "echo c > /proc/sysrq-trigger" command. The requirement is to allow kdb to invoke first after the kernel crash which is not happening now (The system directly gets booted with the dump kernel). Please let me know how to do this. Do we have any patch or steps for it ? You will get more details about my system below: # uname -a Linux mybox 2.6.20smp #1 SMP Mon May 7 11:23:42 PDT 2007 i686 i686 i386 GNU/Linux # kexec -p /boot/vmlinux-dump --initrd=/boot/initrd-dump.img --args-linux --append="root=/dev/hda6 init 1 irqpoll maxcpus=1" # more /proc/sys/kernel/kdb 1 # System Kernel config file: CONFIG_KEXEC=y CONFIG_KALLSYMS=y CONFIG_KALLSYMS_ALL=y CONFIG_KALLSYMS_EXTRA_PASS=y CONFIG_KDB=y CONFIG_KDB_MODULES=y # CONFIG_KDB_OFF is not set CONFIG_KDB_CONTINUE_CATASTROPHIC=0 CONFIG_KDB_USB=y Thanks Preetesh
