Installation with RAID setup always results in "kernel was unable to re-read partition table"

[coCoKNIght]

In Ubuntu 8.10 Server and alternate. When you try to install Ubuntu with a RAID (tested with RAID 1) setup, when writing changes to disk the following warning appears:
---
[!] Partition disks
Warning!
The kernel was unable to re-read the partition table on /dev/md0 (Invalid argument). This means Linux won't know anything about the modifications you made until you reboot. You should reboot your computer before doing anything with /dev/md0.
<Go Back> <Continue>
---
When rebooting the system the same message will come again, but continuing anyway resulted in an operational RAID and Ubuntu instalation.

Aditional information:
I've tested this with SATA HDDs and I think they're unfortunately on the same bus.

The same thing happens in the alternate cd of Hardy Heron x86_64 8.04.2. In 8.04.1 the issue was not present.

This is an old, old, old bug. It may have hidden for a few releases, but I guess now it's back. Details from as far back as 2006 can be found here:
http://article.gmane.org/gmane.linux.ubuntu.server/127
and a *patch* to fix it is here:

According to old postings of mine that I dug up, I already reported this bug here at launchpad, but I'm unable to find my report now.

I see it in Ubuntu Server 8.10 on a Dell Vostro 220 with two SATA drives. (I don't know how they're bussed, they are sda and sdb.)

Happens with Ubuntu Server 10.04 beta as well, error message in attached screen shot. This is a HP BL460 G6 blade with RAID 1+0 setup through a HP Smart Array P410i controller.

Finally i have found a line that suppress that annoying message during installation. Tested in Ubuntu 8.04.4.
