Hello all, First message here, I hope it's the good place to write for this problem. I compile kernel.org vanilla for Debian since 2.4 without big problem, but this time I'm facing a problem that I don't understund the mistake. My goal is to make a kernel without many drivers I don't need and configuration for servers with restriction for many thinks. This kernel need to run en vm guest host (esxi, virtualbox, xen, kvm) and bare metal host on many different brands. Until kernel 4.16.15 everythings works well for all hosts. Since 4.17 to 4.19 all attempts to compile and boot give me an error when boot with the message : 32-bit relocation outside of kernel This error is not well documented, some have error on ram on bare metal host, in my case I have tested wrong kernel in many virualized guest on two plateform with same error, I don't think it's a hardware problem. I join configurations, the first 4.16.15 works very well find here https://dl.digdeo.fr/IoLqo/config-4.16.15-work.txt and for all other version after I have tested upgrade of config file with make oldconfig and localmodconfig but with this all failed, there is config-4.19.16 for exemple that don't work https://dl.digdeo.fr/PzuK7/config-4.19.16-32bit-relocation.txt There is my method to compile kernels : make clean git checkout v4.19.16 cp ../config-4.16.15-work.txt .config export CONCURRENCY_LEVEL=`grep -c '^processor' /proc/cpuinfo` make deb-pkg -j$CONCURRENCY LOCALVERSION=-mykernel KDEB_PKGVERSION=1 dpkg -i ../linux-image....deb reboot Thanks for your help Wallace
