I have been running on 2.4.20 for some time. I just modified my .config, by removing some sections and options, and having make oldconfig fill in the blanks. All goes well with the compile: make clean make mrproper make oldconfig make dep make bzImage make modules make modules_install No problems. Then, I run: update-modules and get: depmod: *** Unresolved symbols in /lib/modules/2.4.20/kernel/drivers/scsi/sg.o depmod: *** Unresolved symbols in /lib/modules/2.4.20/kernel/drivers/scsi/sr_mod.o depmod: *** Unresolved symbols in /lib/modules/2.4.20/kernel/net/8021q/8021q.o This didn't used to happen, prior to the last bout of config changes. I tried configuring with and without modversions set and not, with no difference. Probably not enough information, but what are thoughts? Thanks Luke
