Now I'm trying to do kexec -p /data/l/linux/vmlinux --args-linux --append="init=/bin/bash kexec_jump_buf_pfn=`cat /sys/kernel/kexec_jump_buf_pfn`" but it tells me: Invalid memory segment 0x100000 - 0x7a0fff (and nothing in dmesg) If I try to load bzImage (corresponding to vmlinux I tried to use), I get: root@amd:~# kexec -p /data/l/linux/arch/i386/boot/bzImage --append="init=/bin/bash kexec_jump_buf_pfn=`cat /sys/kernel/kexec_jump_buf_pfn`" Could not find a free area of memory of 9000 bytes... locate_hole failed root@amd:~# What am I doing wrong?
