Bug Description
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?
