Not sure if it is related but the following has happened since recent upgrade to kernel 3.2.0-35-generic-pae. Once it happens the machine has long pauses between certain operations (GUI updates like alt-tab, responding to command-line commands like lsb_release -a, and file accesses such as directory reads) as if it waits for something and times out before responding.
Again, is it possible that disk errors are not being properly understood by the kernel or drivers?
