Public bug reported:
While trying to upgrade some of my systems to Ubuntu 12.04 "Precise" I'm
seeing strange hangs of various processes working with files on
nfs4-mounted /home. KDE sessions in particular hang very often on
startup or after short usage.
In hanged state all the processes, accessin
Also, when booting the Precise VM on Lucid host with oneiric kernel I
see the following message in dmesg:
kvm: : cpu0 unhandled rdmsr: 0xc0010001
There are no similar messages for other 10 Lucid VMs, running on the
same host.

Just in case, I'd like to confirm that upgrading the kernel to linux-
image-server-lts-backport-oneiric does solve this problem for me too.

Title:
Thanks for confirming the bug !
As for me, the workaround was to run the VM on another machine with
Intel processor, so that I can start upgrading the main server to
Precise (which, as far as I can tell, does not have this problem).

Yes, in my case both host and guest are 32-bit. PAE is enabled by
default in stock 32-bit server Lucid kernel.
All my computers are running in 32-bit mode and, unfortunately, I can't
easily reinstall OS on them.

May be it is the number of VMs then... Can you run 11 of them ?

I have tried booting Precise cloudimg on one of my Lucid workstations

Nope. In my case this does not help. I just get "Booting a command list"

For a couple of days I'm trying (on and off) to launch Ubuntu 12.04

I have a similar problem trying to launch any Ubuntu 12.04 Precise guest
(built with VMBuilder, downloaded from cloud-images.ubuntu.com or even

Lucid installer also freeses at detecting partitions on 43% (if I
remember well).
Disabling the DMA for the drive (by passing "libata.dma=1" to kernel at
boot time) solves the problem.
Then dmesg says:

May be the fix can be backported to lucid ?
