Hi, I'm running 2.6.34 with kexec 2.0.1 on a Freescale p5020-based system with 8GB of memory. (It's an embedded system and I can't do much about the fact that it's using older software.)
I booted the original kernel with "crashkernel=224M@32M" in the boot args. I then loaded the crash kernel with: ./kexec -p vmlinux.kontron.strip --append="root=/dev/mtdblock0 rw rootfstype=jffs2 panic=5 1 maxcpus=1 noirqdistrib reset_devices" Then I triggered a crash: echo 1 > /proc/sys/kernel/sysrq echo c > /proc/sysrq-trigger When the crash kernel came up, it had "elfcorehdr=48392K savemaxmem=8192M" in the kernel boot args, and "free" showed the system as having 7908652 KB of total memory instead of the expected 224MB. Do I need to manually specify some options to kexec in order to preserve the memory of the original system? I seem to recall that kexec did this automatically on x86 systems.
