I reported a similar problem on Sep 1, but until now got no response.
The system boots, reads the partition tables, starts the RAID and then
kicks one drive out because of errors.

More similar error messages in the old my LKML-mail.

After sdb was removed from the array the system worked normal with
only two drives.
But on the next boot it kicked the second sata_sil24 disk from the
