Bug description:
  TEMPORARY WORK AROUND FOR THIS PROBLEM IN KARMIC: (This is now also in
  karmic-proposed and needs testing feedback):

  1. sudo gedit /lib/udev/rules.d/95-devkit-disks.rules

  2. locate the following lines (about 1/3 the way into the file; search
  for "smart")

  # ATA disks driven by libata
  KERNEL=="sd*[!0-9]", ATTR{removable}=="0", ENV{ID_BUS}=="ata", ENV{DEVTYPE}=="disk", IMPORT{program}="devkit-disks-probe-ata-smart $tempnode"

  3. comment out the second line by adding a # in front, so you should
  have

  # ATA disks driven by libata
  #KERNEL=="sd*[!0-9]", ATTR{removable}=="0", ENV{ID_BUS}=="ata", ENV{DEVTYPE}=="disk", IMPORT{program}="devkit-disks-probe-ata-smart $tempnode"

  4. save the file and reboot

  BUG DESCRIPTION FOLLOWS:

  In the Karmic beta I experience ssd stalls during the boot process.
  It happens almost everytime before xsplash loads and happens again
  frequently between logging into gdm and the desktop loading.  When it
  happens during login I think it is making gnome time out on loading
  panel items as I get errors related to lots of panel items failing to
  load.  If I log out and back in again when the ssd isn't stalled the
  panel items load fine.

  When it happens the following messages appear before xplash (or in
  dmesg when it happens after gdm):

  ata2: lost interrupt (Status 0x58)
  ata2: drained 16384 bytes to clear DRQ.
  ata2.00: exception Emask 0x0 SAct 0x0 SErr 0x0 action 0x6 frozen
  ata2.00: BMDMA stat 0x4
  ata2.00: cmd c8/00:40:cb:60:32/00:00:00:00:00/e0 tag 0 dma 32768 in
  res 58/00:40:cb:60:32/00:00:00:00:00/e0 Emask 0x2 (HSM violation)
  ata2.00: status: { DRDY DRQ }
  ata2: soft resetting link
  ata2.00: configured for UDMA/66
  ata2: EH complete

  I did not have this issue in jaunty with this hardware and I don't
  think it has happened once the system is fully loaded.  I am running
  karmic unr on an Acer Aspire One netbook.
