how to get rid of 'Can t locate module block-major-105'?

[Michael Renner]

Moin,
although the installation performs good I wonder where these error messages 
come from while the harddisk is formated (probably created while 
sbin/setup_harddisks ist running):
Call task_partition
Partitioning local harddisks
modprobe: modprobe: Can't locate module block-major-104
modprobe: modprobe: Can't locate module block-major-105
modprobe: modprobe: Can't locate module block-major-104
modprobe: modprobe: Can't locate module block-major-105
.
.
.
.
and so on, 10 times or more, what appears dangerous to my users.
Any hints?
