> FATAL ERROR: inserting ext3 > (lib/modules/2.6.4-1-386/kernel/fs/ext3/ext3.ko) : Invalid module format > *snip* Sounds like a mismatch between kernel and module versions. Are you sure you installed the modules? Are you sure you are booting the new kernel and not the old ones? Trying moving /etc/modules out of the way so you don't load any (possibly old) modules at all. Also try using the Debian kernel builder package instead of hand-rolling. Alexis
