Title:
  Intel ISW soft raid disk seen, shown in "partition disks," but fails
  to modify (mounted RO)

Status in “debian-installer” package in Ubuntu:
  New

Bug description:
  Kubuntu, 11.10 beta 2, amd64 (CD: kubuntu-11.10-beta2-alternate-
  amd64.iso)

  Disk: RAID 10 set controlled by the Intel PCH. Existing Linux
  installation from which the partition tool correctly picks up
  partition table.

  Takes commands (set partition type/mount point etc) but fails to
  modify and therefore is stalled.

  The description of the disk is

  "RAIDmd126 device #:RAIDactive device #(read-only)RAID10 device .."
  followed by incomplete list of sda/b/c/d

  The #(read-only) looks ominous to me...

  The Linux install I use at the moment uses DM (not MD), so I tried
  rd_NO_MDIMSM and rd.md.imsm=0 options inspired by advice already
  received with other distributions.

  Best Regards

  Jens
