The problem is in the debian installer, if you answer the question with No and
go to a shell:

~ # insmod /lib/modules/3.16.0-4-amd64/kernel/fs/ext4/ext4.ko
insmod: ERROR: could not insert module /lib/modules/3.16.0-4-amd64/kernel/fs/ext4/ext4.ko: Unknown symbol in module

The installer is provided by the 'elbe-bootstrap' package. Probably Debian
uses a new kernel in Debian 8.10 released on 9th of December. So the old
Kernel provided by elbe-bootstrap is not able to load the 'newer' kernel modules
downloaded from the configured primary mirror.
