I'm not sure other modules are missing : my server correctly starts, I = then only overwrite ZFS module (/boot/kernel/zfs.ko), I think it should = then work. But server hangs during startup, certainly because module compiled = directly using make is different from the one built with make = buildkernel (which works). As says Xin below, some options from sys/*/conf/GENERIC may not be taken = into account with the quick make method... I'll try to give the faulty module a try on a non-zfs root machine. The -DNO_CLEAN method is interesting if src tree has not been cleaned = before :) (I always do a make clean to leave the tree cleaned ^^) So sounds like there is no solution but trying to speed-up a whole = kernel build. Thank you !
