It may be a few weeks before I can run tests with the very latest
kernel.  Also, since finding out that the linux-image-lowlatency package
works, we haven't done much more testing, but it was still having
problems on the generic kernel the last time we upgraded to a new
version of Ubuntu about half a year ago.  We also still haven't tested
with a hard drive to see if the problem exists there as well or if the
laptop only has the problem with that particular SSD.

Title:
  11.10: ata1: Link is slow to respond

Status in The Linux Kernel:
  Confirmed
Status in “linux” package in Ubuntu:
  Incomplete

Bug description:
  I have a friend who is getting ata1: Link is slow to respond on an
  Acer Aspire 5560G laptop and an SSD with Ubuntu 11.10 (latest updates
  as of 27 March 2012) and 12.04 beta1 livecd at bootup.  Once this
  happens the laptop has to be power cycled to get the SSD working
  again.  On Ubuntu 11.04 and previous versions and System Rescue CD
  kernels the laptop boots without any problems.

  The SSD is a AR120GBE and the AHCI controller is 1022:7804, subsystem:
  1025:059f

  Have also tried adding libata.force=norst libata.force=0:norst
  libata.force=1:norst libata.force=2:norst to the grub boot option
  although not sure if that is the correct set of parameters.

  WORKAROUND: linux-image-lowlatency package with Ubuntu 12.04 as that
  has CONFIG_HZ=1000 which appears to work without any problems.
