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.)

Thanks in advance,
