Bug Description

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:
http://groups.google.com/group/linux.debian.bugs.dist/browse_frm/thread/9d640dd46c19d081/db0acb6616203668%23db0acb6616203668

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.)

Changed in debian-installer:
status: New → Confirmed

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.
