no such device address

[Hadders]

Hi all,
  Trying to get my Intel SATA RAID Container working with the latest kernel.

In runlevel 1, if I do a mkinitrd I get the error message:

device-mapper: deps ioctl failed: No such device or address
_deps: task run failed for (253:0)

Not sure what to do?

Thanks for any advice. Hadders
