Hi.
I haven't rebooted my laptop with kexec for quite some time, but when I tried
to this morning I got the error you will
see in $SUBJECT. The error occurs with both kexec-tools-2.0.17 or -2.0.16 run
on either 4.18.0-rc6+ (built from a git
pull this morning) or 4.14.57 kernels.
I searched for "R_X86_64_PLT32" and found that there was a change to the kernel
that may be related -
b21ebf2fb4cde1618915a97cc773e287ff49173e x86: Treat R_X86_64_PLT32 as
R_X86_64_PC32. So I replicated the change that
patch made to arch/x86/kernel/machine_kexec_64.c in
kexec/arch/x86_64/kexec-elf-rel-x86_64.c and kexec now reboots into
the new kernel.
I don't know enough about relocations and the like to know whether my 'fix' is
correct and the best way to go about it,
but I've included it below for your consideration.
