            Bug ID: 195231
           Summary: Continuous messages of "*ERROR* UVD not responding,
                    trying to reset the VCPU!!!" and frozen screen
           Product: Drivers
           Version: 2.5
    Kernel Version: 4.10.3
          Hardware: x86-64
                OS: Linux
              Tree: Mainline
            Status: NEW
          Severity: normal
          Priority: P1
         Component: Video(DRI - non Intel)
          Assignee: drivers_video-dri@kernel-bugs.osdl.org
          Reporter: rbrito@ime.usp.br
        Regression: No

Hi.

First of all, I'm not sure if I selected the correct category when filing this
bug. I don't mind being corrected here.

OK, now, to the actual bug report.

My mother has a Dell Inspiron 15R N5110, which has an intel Sandy Bridge
integrated card and an AMD Radeon card (if I'm not mistaken it is reported as
an HD6400 series card, not being more specific).

According to my mother, it was working correctly with an Ubuntu running their
kernel 4.4 until it started only showing a black screen about 15 days ago.

I took her notebook and saw that the problem is that the kernel is now showing
many times the message "*ERROR* UVD not responding, trying to reset the
VCPU!!!" and the graphical environment does not completes loading.

I tried using Ubuntu's precompiled and unpatched 4.10.3, but the problem
persists (in fact, I was ping-pong'ing with many kernel versions to see if
something worked).

Besides working around the issue with radeon.modeset=0, so that the computer
can successfully boot, I don't know what to do to fix this issue, but I can
provide as much information as needed about it.

The unfortunate thing with the radeon.modeset=0 (that wasn't necessary, say,
about one month ago) is that she can't play some games that she used to and
that's her only entertainment, after having been diagnosed with some serious
illness. :(

Again, I can provide as much information as needed.


Thanks,

Rogério Brito.

Please attach your xorg log and dmesg output.  Does appending radeon.runpm=0 on
the kernel command line in grub help?

Dear Alex,

(In reply to Alex Deucher from comment #2)
> Please attach your xorg log and dmesg output.  Does appending radeon.runpm=0
> on the kernel command line in grub help?

I'm attaching them.

The dmesg output shows an Ooops when I start X from a command line. I had to
arrange things via SSH, since the keyboard stops responding and, sometimes, the
kernel reboots the system.

Regarding your question, appending radeon.runpm=0 does help. The Oops is
absent, but "UVD not responding messages are still present". At least, the
system boots up to the desktop and it works, but I don't quite know how to
check which card is working at a given point in time (if the Intel one or the
if the radeon card).

Thanks,

Rogério.

Dear Alex and other developers, do you need any extra information from me? I
will do my best to gather anything that may be helpful in fixing this bug.


Thanks,

Rogério.

I just installed Ubuntu's precompiled and unpatched kernel 4.11-rc5
and the messages of "UVD not responding" like in the subject persist,
also with the whole system hanging.

If I append radeon.runpm=0, the system does boot, but the messages are
still there. It is, though, taking ages to boot, compared to what it
used to be.

Once again, if anybody wants me to try any kernel, just tell me and I
will do my best.

I will update the information that I grab and/or those that people ask
me and put those at this bug on bugzilla
(https://bugzilla.kernel.org/show_bug.cgi?id=195231).


Thanks,

Rogério.

Well bisecting which patch caused the break would be a good idea.

To start that I suggest you try to compile kernel 4.4 by yourself first.

That should also yield a temporary solution until we can narrow down the root
cause.

First of all, I hope you don't mind that I'm including my mom here, so
that she can follow how her computer is doing, or, rather, what I am
doing with her computer.

I tried using Ubuntu's unpatched/precompiled kernels 4.2, 4.4, 4.8,
4.10 and 4.11-rc5 and, apparently, they now always show this message
*and* it frequently freezes to the point that no magic Sysrq keys
work, sometimes the caps lock kernel blinks and so on.

Booting with radeon.modeset=0 allows the computer to boot to the
desktop environment, but makes the CPU so hot when she plays her
flashplayer-based games that the kernel shows many messages of thermal
limit being reached and CPU speed being throttled.

Booting with radeon.runpm=0 still gets me all the error messages
listed in the subject (and present in the logs that I sent to
bugzilla), but the temperature *seems* to be slightly lower (not
enough testing was done with this configuration).

I don't know how to see/check what GPU is being used at a given time:
if the Intel GPU or if the AMD GPU...

So, given that the problem now seems to be present with all those
kernel versions that I tested, is it worthwhile to compile my own
kernels?

As before, I will try to do whatever I'm directed to.


Thanks a lot,

Rogério.
