[1.] One line summary of the problem: 
Desktop PC freezes after showing many times the lines "AMD-Vi:
Completion-Wait loop timed out" and "BUG: soft lockup - CPU#2 stuck for
23s!"

[2.] Full description of the problem/report: 
During Linux installation on a Desktop PC Medion MS-7857 the kernel was
hanging during boot and during the installation. 

I could see many times the following lines repeated very quickly in the
console:
AMD-Vi: Completion-Wait loop timed out
AMD-Vi: Completion-Wait loop timed out
AMD-Vi: Completion-Wait loop timed out
AMD-Vi: Completion-Wait loop timed out

And occasionally the following lines appeared in the system logs (dmesg
output):

   28.145206 AMD-Vi: Completion-Wait loop timed out

This behavior remained after the installation of several linux distributions
like: Ubuntu, Fedora, Debian and openSUSE. Finally I decided to work with
Ubuntu and report a bug with them:
https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1280668

The issue remained after updating all applications and after updating the
kernel with the newest upstream mainline kernel:
~kernel-ppa/mainline/v3.15.2-utopic

The system freezes for long periods of time and makes the computer unusable.


Also, I can't boot this computer normally because it freezes with a black
screen. The only way to complete the installation process was passing noapic
as a boot parameter. The PC still hanged but for shorter periods of time and
then continued working.
With Ubuntu I tested installations with several versions and I found the
following:
.	Ubuntu 10.04.4 LTS (Lucid Lynx) was unable to boot the PC due to a
Kernel panic.
[0.812538] Kernel panic - not syncing : AMD-Vi : ILLEGAL_COMMAND_ERROR while
resetting command buffer
.	Ubuntu 10.10 (Maverick Meerkat) was unable to boot the PC due to a
Kernel panic. But I wasn't able to capture the error.
.	Ubuntu 11.04 (Natty Narwhal) was unable to boot the PC due to a
Kernel panic. And I wasn't able to capture the error.
.	Ubuntu 11.10 (Oneiric Ocelot) was able to boot up and hang up for
more than 20 minutes. I wasn't able to work with the computer or get any
logs. However, the last message in console was:
[147.992078] AMD-Vi : Completion-Wait loop timed out
It seems that the problem appeared for first time in the Ubuntu release
11.10 (Oneiric Ocelot), because with previous Ubuntu versions this PC was
unable to boot.

[5.] Output of Oops.. message (if applicable) with symbolic information
resolved (see Documentation/oops-tracing.txt) 
Not sure if this is part of the oops-tracing. However, I have a complete
dmesg.txt file that I can send to you with all the instances that the BUG
appeared. These are some examples, please see below:

Hey Kevin,

most likely the BIOS is buggy and does not setup the IOMMU hardware
correctly so that it can't be used reliably in Linux. You can try to
update the BIOS the the latest version and see if it fixes the issue, if
not you should disable the IOMMU in the BIOS to get rid of the problem.

Or you pass 'amd_iommu=off' on the kernel command-line to disable the
AMD IOMMU driver in the Linux kernel.

Thank you Joerg and Borislav,

There is no BIOS Update available for this Mother Board. It has the most
recent from Jan 2014. And I didn't find any option available in the BIOS
Menu to disable the IOMMU.

I tried yesterday a fresh install passing the 'amd_iommu=off' to the kernel
and everything is working fine. No delays/hangs, etc. The workaround works
just perfect.

Again thank you very much for your help! 

Kind regards,
Kelvin González

Subject: Re: Desktop PC freezes after showing many times the lines "AMD-Vi:
Completion-Wait loop timed out" and "BUG: soft lockup - CPU#2 stuck for
23s!"

Hey Kevin,

most likely the BIOS is buggy and does not setup the IOMMU hardware
correctly so that it can't be used reliably in Linux. You can try to
update the BIOS the the latest version and see if it fixes the issue, if
not you should disable the IOMMU in the BIOS to get rid of the problem.

Or you pass 'amd_iommu=off' on the kernel command-line to disable the
AMD IOMMU driver in the Linux kernel.

Btw, please do not top-post when replying to that thread.

Well, this disables the IOMMU on your machine and it works perfectly
because you're simply not using it anymore. :-)

If you get a BIOS update at some point and/or want to complain to the
board manufacturer to give you a BIOS update and to fix the IOMMU setup,
you could try to enable it again (i.e., remove the cmdline option) and
report back to us.

Thanks.
