The resierfs filesystem is trying to access beyond the end of the
raid1 array.  Maybe some indexing information in the array is
corrupted.
Did you recreate the array (mdadm --create) after changing to the new
drivers?  If so, could you have accidentally made it a little smaller?

Possibly try running fsck and see if it finds anything to fix.
