Hi SailorMH,
We always compile the most things in the kernel so we don't have many modules in the kernel modules directory. It could be that Debian needs the LVM and RAID support (CONFIG_MD and CONFIG_BLK_DEV_DM/dm-mod) as modules. We compiled these in the kernel directly. CONFIG_DM_RAID and CONFIG_BLK_DEV_MD aren't set. Have you seen which modules are missing? I could compile them for the next kernel release.
Thanks,
Christian
