dmraid ISW maximum partition size?

[Danny]

On my ICH8R controller I have a 1.5TB partition and it works fine on
the latest Ubuntu with stock dmraid packages.
Is it possible that you are creating the 875GB partition larger than the device?

Try creating a 874GB partition, its possible that you are being
affected by the bug phillip was discussing on this list the other week
where it actually calculates the device size in a funny way.
