dmesg output

Hi there,

I’ve got a new laptop since a couple months, and I’m starting to configure it intensively and report bug. It’s an HP zBook Studio G3, with a Core i7-6700HQ with Intel HD graphics and a dedicated NVIDIA Corporation GM107GLM [Quadro M1000M] card. Amongst the issue I find in dmesg, there is those two lines that appear in red:

[ 16.246988] nouveau 0000:01:00.0: priv: HUB0: 614900 00800000 (18408200)
[ 16.248921] nouveau 0000:01:00.0: bus: MMIO read of 00000000 FAULT at 022554 [ IBUS ]

I’ve attached the full dmesg.

Should I open a new bug with "FAULT at 10eb14" or is it this same issue?

@gene, Johnny B. Goode: From what I know, the “at” value matters, because they have meanings. Though from one generation to another this could be different values for the same register.

Also, @Johnny, in your case it’s a write instead of a read, so I would definitively open another issue.

Confirm. I get the same message with the same number (3e6684) using latest Debian testing with GeForce GTX 750 Ti:

01:00.0 VGA compatible controller: NVIDIA Corporation GM107 [GeForce GTX 750 Ti] (rev a2) (prog-if 00 [VGA controller])

I'm not using any proprietary drivers. My current xserver-xorg-video-nouveau version is 1:1.0.15-2.

I've been getting this message for some months now during boot, only now took a picture and tried to search online - this is the only place. This message shows only for a blink of a second during boot, after filesystem check, and then continues to boot normally. Haven't noticed any misbehavior of GPU after machine has booted.

Looks like 22554 is no longer available on Maxwell. See where ltc reads it from for the new location. Needs to be split out of ramgk104 somehow.

I have WIP patches in my Fermi reclocking code (I'll try and push before I leave for xmas break) that begin to address this.

This also affects me.
Fresh install of Ubuntu Mate 16.04.3

AMD FX 8350
GeForce GTX 750TI (using the included nouveau drivers)
2Tb Seagate HDD
16Gb Corsair DDR3

I cannot post anything as it fails after grub and goes to BusyBox.
But I can run dmesg and cannot see anything unusual.

Not sure if this is related but, this is after install failed 3 times on USB, finally had to install via disk and install without wifi to make it work. The install would freeze and static would come out the speakers. That also happened the first time I rebooted and now when I reboot this error occurs.

Yes please, where there appears a new register on differing hardware family.

It's an easy operation to merge bugs later on should they be due to the same underlying cause, but almost impossible to separate them out.

Hi folks,
I have the very similar issue about drm, bus read FAULT, etc. However, my problem is more severe than just red lines in dmesg.

I have ideapad 700 with HD Graphics 530 as the integrated and GeForce GTX 950M as the discrete card. I sit on gentoo with Linux-4.15.1.
The first point is that if I use nvidia drivers than my brightness buttons do not work (not visible for anything). Summing this up with the total no need of a powerful graphics I decided to go to the bumblebee just in case I will indeed need a better gpu in action. That is to fire up the discrete card on demand.

My problem is that upon starting some glx-aware program at the moment when bumblebee is trying to start a separate hidden X server with nouveau as the driver my primary X server restarts.
After this restart and in attempt to run some glx-aware program again I see X errors and nothing good. They boil down to the fact that drm cannot ecquire an access to card0 and card1 because of permission issues. Well, the primary X server now does not restart though.

I tried all what bumblebee guys suggest - no way. Also, everything is smooth with the nvidia driver in this config.

I think it is those red messages in dmesg are the primary indicator of my troubles.

@Alex You should not use Bumblebee with nouveau. Also your bug is similar to an old of mine: https://bugs.freedesktop.org/show_bug.cgi?id=98384. So part of your issue is that your system is likely not up-to-date.

But the correct solution is to not use nouveau with Bumblebee. And in any case, it has likely nothing to do with this issue. ;)

@Bruno, thanks for the comment. I will check it out. Bumblebee: you see, I'm fine with intel, I do not need extreme speeds and I have 16GB in RAM ...
nvidia - I could manage to install it either globally or in bumblebee but it blocks the brightness control when used permanently - very weird, so only bumblebee would go.
Something went wrong with setting nouveau globally and I have given up. Will retry. But it will not suit me if the brightness keys are blocked ...
And yes, my system is nearly the tomorrow's version. It is up-to date. At least the kernel is the one released few days ago ...

With nouveau loaded (assuming things go properly), your GPU should suspend when not in use.

This is included in https://bugs.freedesktop.org/show_bug.cgi?id=98386. And apparently also https://bugs.freedesktop.org/show_bug.cgi?id=108980, which seems recently fixed.

This is like https://bugs.freedesktop.org/show_bug.cgi?id=100423#c19, not sure if there is already an issue for it.

Tonight I tried to see what happens if I generate a xorg.conf file and place it in /etc/X11/xorg.conf, as described here:
https://askubuntu.com/questions/4662/where-is-the-x-org-config-file-how-do-i-configure-x-there

When I do that X starts without the error cannot find framebuffer device. It starts with a backtrace list and then stops with:

'Segmentation fault at address 0x0.

Fatal sever error etc etc etc.

Hope this helps!

The machine is an ASUS UX501V with an Intel HD Graphics 530 + NVIDIA GTX 960M (more details below). I'm running an up to date Debian 9.9 with a 4.19.28-2~bpo9+1 kernel (from stretch-backports). It is usually plugged to an external screen though HDMI (32" AOC Q3277PQU at 2560×1440).

The last line is repeated hundreds of times.

It may be related, but am not sure: right after a boot, the graphics (e.g. GNOME Shell animations) are fast and smooth, but after a while (I think it's related to the machine going to sleep, and/or the screen being locked), it seems to go to a fallback non-accelerated mode. It's still usable, but even moving a simple terminal window is slow. Strangely, even in this degraded mode, scrolling full-screen pages is still smooth in Firefox, as is e.g. watching videos.

This is concerning that after all this time (2,5 year) this issue is still here.

I have the same issue shown in journalctl. I believe it wasn't there from the start but showed a while ago. I don't see any problems on the frontend site, however.
I have a hybrid GPUs and currently use optimus-manager to switch between GPUs. Nouevau is making the switch (successfully).

Here is the bug:
