[Launchpad Bug Tracker <1451277@xxxxxxxxxxxxxxxxxx>]

You have been subscribed to a public bug:

On Kubuntu, 64 bit AMD Phenom2 machine with 4 cores, and old (Geoforge 7025) Nvidia graphics.
Using LVM. Machine also has a 2 disk software raid (mirroring).

The machine was working fine before the upgrade, now it is almost
impossible to use it... I see Wait in Top always above 60%; in dmesg
after a few minutes that the machine is up even if the machine does
nothing. I see hung processes (typically vgs, but occasionally also
others).  LVM related commands (e.g. lvdisplay) almost always hung at
the terminal. I also see in ps some kernel workers almost constantly
stuck in D state. Also, the machine takes ages to shutdown.

Issue remains there also if I disable X (switch off the X login manager,
sddm) and check at the console.

Sorry I cannot provide details with apport, but the machine has been
switched off and I will not be able to take it up again before a few
days from now.

The symptom I am observing may also be a sign of failing hardware, so
please leave the bug as unconfirmed until I make some more tests or
someone provide details on similar issues. In the meantime I would like
to see if others are experiencing a similar serious issue. Is there
anything specific that has changed between utopic and vivid, I should
look into?
