Title:
  [Lenovo ThinkPad W530] I/O slow down

Status in “linux” package in Ubuntu:
  Incomplete

Bug description:
  Since at least 12.10, symptoms are that as time goes by I/O gets
  slower and slower (primarily if not even only writes rather than
  reads). It can be temporarily cured via /sbin/sysctl -w
  vm.drop_caches=2 and/or /sbin/sysctl -w vm.drop_caches=3 but the
  problem will re-appear again sooner rather than later. The problem
  seems also somewhat proportional on how much RAM is allocated. It does
  not seem to appear with less than 8GB (i.e., i saw it first when
  switching to a 16GB laptop/ThinkPad w530) and is considerably worse
  when allowing all memory compared to, e.g., by using only ~14GB using
  the mem=14000M  boot option.
