Hi,

I'm trying to initialize a raid device, but something in my setup must 
be wrong. Here is a part of 'messages' log:

I've 4 SATA Seagate disks connected to Silicon Image SATALink 3114 and 
the machine is running few days old amd64 kernel 2.0_STABLE. I've tried 
three of the disks in all possible combinations to make raid1 device 
from two of them. The error is always the same including the number of 
errorneous fsbn - '268230592'. I am definitely doing something wrong.

Thanks for any advice.
