I've got an ultra5 happily running gentoo.
Since I have extra space on its hard drive, I'm trying to add a new partition
but fdisk keeps telling me this strange message:

WARNING: Re-reading the partition table failed with error 16: Device or
resource busy.
The kernel still uses the old table.
The new table will be used at the next reboot.

...And after the reboot, the new partition is gone...
(and I know that you normally don't need to reboot to add a new partition
under linux)

Any idea of what is going wrong with my sparc box?

Below is a transcript of the operation:
