Hi experts, I have a problem when using kexec-tools on freescale powerpc P1014E. I have 256MB memory and reserved 78MB for crashkernel. The cmdline for production kernel is, bver=0.0.10 root=/dev/ram rw console=ttyS0,115200 crashkernel=78M I used below command to load crash kernel into memory. /mnt/uspace/abc/kexec -d -l /mnt/uspace/abc/vmlinux.z.img \ --initrd=/mnt/uspace/abc/ramdisk.img.gz \ --append="root=/dev/ram1 rw console=ttyS0,115200 1 maxcpus=1 noirqdistrib reset_devices" Then I used "kexec -e" to execute the crash kernel. The crash kernel works *well* and I can enter busybox after the crash kernel is up. But when I used below command to load crash kernel into memory for panic catching, /mnt/uspace/abc/kexec -d -p /mnt/uspace/abc/vmlinux.z.img \ --initrd=/mnt/uspace/abc/ramdisk.img.gz \ --append="root=/dev/ram1 rw console=ttyS0,115200 1 maxcpus=1 noirqdistrib reset_devices" and tried to trigger panic by "echo c > /proc/sysrq", system hung after "Bye!" was printed to console. I attached the debug output of "kexec -d -l" and "kexec -d -p". Can someone please help here or point me a correct place to post the question? Thanks. BR
