Hi, The kernel rpms for RHEL5 builds (e.g. kernel-lustre-smp-2.6.18-8.1.14.el5_lustre.1.6.3.x86_64.rpm) contain debug symbols. e.g. size of supplied ext3.ko binary is 2473096 -- after running strip it is 144808 Is there any reason for this? Builds for other OS variants come without symbols. Regards, Mirko
