[Bug 595047] [NEW] massive i/o renders the system unusable

[Launchpad Bug Tracker]

You have been subscribed to a public bug:

Periodically I notice my system slows to a near stand still, and the
hard drive light is constantly going.  This seems to be a massive amount
of disk i/o and it lasts for a long time (lets say 30 mins to put a
number on it).  I installed and ran iotop (`iotop -a`) and it seems to
point to jbd2.  From what I can see jbd2 is related to ext4 journaling,
but I cannot figure out how to kill this operation.  It might even be a
red herring because I have also stopped the disk activity by kill either
chromium or firefox.  I need to understand what else I can do to
troubleshoot this.
