Help needed, please: Sandy Bridge. 2.6.27.21 kernel x86_64 toolchain built from crosstools-ng. Using relocatable bzImage as first kernel as well as crash kernel. # cat /proc/cmdline rw root=/dev/sda3 rootwait console=ttyS0,38400 crashkernel=128M at 16M # kexec -l /boot/bzImage --reuse-cmdline Unhandled rela relocation: R_X86_64_PLT32 Why?? I fooled around in kexec-elf-rel-x86_64.c and noticed there's no case for that r_type, so I added it as a fall-through to one of the existing ones. Then I got this: # kexec -l /boot/bzImage --reuse-cmdline Unhandled rela relocation: R_X86_64_GOTPCREL Strange. So I added that to the fallthrough, and then suddenly it seemed as if the crash kernel was getting loaded OK (no error messages anymore). But then I tried: # kexec -l /boot/bzImage --reuse-cmdline # kexec -e [ 952.817842] md: stopping all md devices. [ 953.818808] sd 0:0:0:0: [sda] Synchronizing SCSI cache [ 953.961590] igb 0000:02:00.0: PME# enabled [ 953.962395] igb 0000:02:00.0: PME# enabled [ 953.976468] Starting new kernel After several seconds pause, it ended up back at GRUB, which I didn't expect. Any help would be most appreciated - thanks.
