Well... if you shut down your system cleanly, you should not be doing
recovery, so something is still not right (assuming that the messages
you posted were after a normal shutdown).

Whoops, a couple things.  first, it's "BLKBSZSET" that I was thinking about,
but I don't think you'd see this at boot time in any case.

It would be nice if the ataraid driver printed out _which_ ioctl was
unsupported...  in pdcraid.c you could change the

printk("Invalid ioctl \n");

line to

printk("ataraid: invalid ioctl cmd=%x %lx\n", cmd, arg);

if you wanted to chase this down, although I don't know if it's related
to your problem.
