Hi,
finally I've setup my dmraid system on A8r32-MVP and SiliconImage controller because of unsupported ULI tech. All gone well, but looking at /var/log/messages there are these line for each sturtup:

   Dec 22 22:05:11 NeXT Buffer I/O error on device sda4, logical block
   160633728
   Dec 22 22:05:11 NeXT attempt to access beyond end of device
   Dec 22 22:05:11 NeXT sda: rw=0, want=290438930, limit=145226112
   Dec 22 22:05:11 NeXT Buffer I/O error on device sda4, logical block
   160633729
   Dec 22 22:05:11 NeXT attempt to access beyond end of device
   Dec 22 22:05:11 NeXT sda: rw=0, want=290438931, limit=145226112
   Dec 22 22:05:11 NeXT attempt to access beyond end of device
   Dec 22 22:05:11 NeXT sda: rw=0, want=290438932, limit=145226112
   Dec 22 22:05:11 NeXT attempt to access beyond end of device

These are the line releted to the disks in raid:

Pleace note that sda has its-own partitions instead sdb has unknown partition table.

Do you know where is the fault?
