Hi experts, I'm trying to get kexec 2.0.9 built with musl-libc to work with my customized kernel, but failed with no luck: the error for i586 is: my_load:667: do Could not find a free area of memory of 0x9000 bytes... locate_hole failed the error for x86_64 is: Overlapping memory segments at 0x400000 sort_segments failed Nothing has been loaded! I did many tests on various combinations, and find below configs work: * kexec.musl can work well with Ubuntu kernel, but can't work with my kernel; * kexec.eglibc can work well with both Ubuntu kernel and my kernel; The issue seems to be related with both kernel/libc, I'm curious on: 1) what must be in kernel for kexec to work? it's a trimmed down kernel for embedded devices, so I may turn off something wrongly. (however this can't explain why kexec.eglibc works with the same trimmed kernel) 2) what conditions must be meet in libc/compiler for kexec to work? Thanks for your help in advance! BTW: 1) kexec.eglibc is built manually in Ubuntu 14.04, v2.0.9; 2) kexec.musl is built using Yocto recipe, v2.0.9 (http://layers.openembedded.org/layerindex/recipe/4861/); 3) I tried both static link and dynamic link, same results. 4) Ubuntu kernel is vmlinuz-3.13.0-32-generic, uLinux kernel is bzImage--3.19 -- Regards, Yan
