Comment 4 for bug 365702

This bug is NOT invalid - please reopen.

I have the same issue on Lenovo Ideapad S10e not being able to install Ubuntu 9.04 Netbook Remix.

Partition table as shown in text console #2 when installer started up:

> fdisk -l
Disk /dev/sda: 160.0 GB, 160041885696 bytes
255 heads, 63 sectors/track, 19457 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Disk identifier: 0xe41dfeb7

   Device Boot Start End Blocks Id System
/dev/sda1 * 1 3004 24121597 7 HPFS/NTFS

> ls -l /dev/sda*
brw-rw---- 1 root disk 8, 0 2009-10-25 15:47 /dev/sda
brw-rw---- 1 root disk 8, 1 2009-10-25 15:47 /dev/sda1

brw-rw---- 1 root disk 8, 7 2009-10-25 15:47 /dev/sda7

I chose manual partition and set

  /dev/sda5: ext3, format yes, mount point /
  /dev/sda7: ext3, format yes, mount point /home

*********************
In Summary page before hitting the "install" button it says (translated from german to english):

  Partition table of the following devices was changed:
   SCSI3 (0,0,0) (sda)

Thats WRONG - i did NOT change any partition table in the installer - i just selected existing partitions to be formatted.
I didn't create partitions, i didn't delete partitions, i didn't resize existing partitions.

So the installer should not - i repeat, NOT - change anything at all regarding the existing partition table!
*********************

What now happens affter hitting "install" button:

The installer deletes some partitons and creates them again (WTF?) and then tells the kernel to reread the partition table
of /dev/sda - which FAILS:

> ls -l /dev/sda*
brw-rw---- 1 root disk 8, 0 2009-10-25 16:12 /dev/sda
brw-rw---- 1 root disk 8, 1 2009-10-25 16:12 /dev/sda1
brw-rw---- 1 root disk 8, 2 2009-10-25 16:12 /dev/sda2

> fdisk -l
Disk /dev/sda: 160.0 GB, 160041885696 bytes
255 heads, 63 sectors/track, 19457 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Disk identifier: 0xe41dfeb7

The installer does notice that something went wrong:

  Error informing the kernel about modofications to partition /dev/sda5 -- Device or resource busy ...

I hit button "Ignore".

Next thing error message appears, telling me mkfs on /dev/sda5 went wrong - no wonder since device file /dev/sda5 does not exist...

Please fix the installers partition module.
