Reconfiguring the RAID lets me restart the whole process. Following up to myself, I compiled my own kernel 2.6.11.11 and things appear to work so far. Known problem that has been fixed, or worth investigating? I would also appreciate pointers to sites, mailing lists, or people likely to know how to configure things for maximum speed. (I've got two SATA RAID controllers with 6 discs each, and I need > 300MB/s reading speed through the filesystem. So far, I was thinking of doing XFS over MD-RAID0 over two hardware RAID0, and things look rather promising.)
