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.
