Unable to load...

[Dan Dragut <dand@target.zone.ro>]

I have this problem at boot time (dmesg):

[...]
i2c-core.o: i2c core module
Linux video capture interface: v1.00
i2c-core.o: adapter saa7146(1) registered as adapter 0.
saa7146_core.o: saa7146(1): bus:0, rev:1, mem:0xc284c000.
saa7146_core.o: 1 saa7146 chipset(s) found.
i2c-core.o: driver dvbi2c registered.
Unable to load 'Root'.
Failed to read 'root'.
commandrequest error
dvb: firmware = 00000000
dvb: MAC = 00 d0 5c 3d 10 f5
dvb: attach_adapter
dvb: 1 dvb(s) found!
[...]

followed by an 'outcommand error '. If I do 'make rmmod' and 'make insmod' 
in the directory where I keep the drivers, things go back to normal.
Please, can you tell how to solv this problem?!

Thank you,
Dan
