asynchronous wait on fence NVIDIA:nvidia.prime:7d9 timed out
Since I installed kernel 4.14.7 I'm getting this error on logs (asynchronous wait on fence NVIDIA:nvidia.prime:7d9 timed out) but more importantly the machine freezes unpredictably, even if not randomly. The freeze can happen, say, when using xrandr to manage a second monitor (using xrandr because I'm on kde and kscreen2 does not play nice with nvidia). Quite often the freeze happens when moving mouse across screens (sometimes it recover, though). I saw this happen also when booting, likely when kms stuff kicks in. Actually, removing nvidia-drm.modeset=1 and splash from kernel command line avoids the freezing. It seems that running nvidia-config and moving screen around avoids further lockups, but it could be only a coincidence. This was not happening with kernel 4.14.6 and earlier.

I think you just need newer firmware files for your iGPU: [code][ 1.609409] i915 0000:00:02.0: Direct firmware load for i915/skl_dmc_ver1_26.bin failed with error -2 [ 1.609410] i915 0000:00:02.0: Failed to load DMC firmware [https://01.org/linuxgraphics/downloads/firmware], disabling runtime power management.

Not really sure about that, for a couple of reasons: [olist] [.]This error message (failed to load the firmware blob) is happening on my logs since kernel 4.14.3, and the faulty behaviour for the card started only with 4.14.7 (and goes on with 4.14.8)[/.] [.]It seems to refer to runtime power management. Admittedly not ok, but I wonder if this can cause the reported behaviour also.[/.] [/olist] Anyway, good catch, I will try to understand why the firmware is not loaded when the file is actually there.
Not really sure about that, for a couple of reasons:
  1. This error message (failed to load the firmware blob) is happening on my logs since kernel 4.14.3, and the faulty behaviour for the card started only with 4.14.7 (and goes on with 4.14.8)
  2. It seems to refer to runtime power management. Admittedly not ok, but I wonder if this can cause the reported behaviour also.


Anyway, good catch, I will try to understand why the firmware is not loaded when the file is actually there.

Just for info, I'm running 4.14.7 on Haswell with Prime sync and don't experience your issue. Looking at the commits between .6 and .7 (not that many) there's nothing that would explain this. But without the firmware, you might have to set i915.enable_rc6=0 to work around problems. Though it's strange why this is happening just now.

I think the oops is unrelated, rather suspect intremap=no_x2apic_optout for that. Regarding firmware, maybe you now need an initrd for it?

I finally managed to load the firmware correctly, but I'm still getting kernel oopses (see below). should then I assume that the issue that I'm experiencing is connected to x2apic setting and not to other nvidia stuff?

I just made some other tests; now the firmware for intel card is loaded fine, but the issue is still present. this happens with or without x2apic optout and with or without i915.enable_rc6=0 parameter. The only way to avoid lockups when using xrandr to configure the external monitor is to remove nvidia-drm.modeset=1 from the kernel boot parameters. Interesting enough, the issue is much more evident when the laptop is inserted into a docking station, and also in this case it could randomly happen that (say, 1 out of 10) xrandr works without screen lockup, so it seems quite likely that a timing issue is involved...

Did you ever try if reverting to kernel 4.14.6 really fixes the issue?

not really, You are right. Will try asap.

So, it seems that even older kernels (4.14.6) shows the same behaviour, you were right. I guess that I overlooked some other change. To summarize, in my setup when nvidia-drm.modeset=1 is present, changing monitor layout with xrandr, like xrandr --auto and xrandr --output eDP-1-1 --pos 0x70 --primary --output DP-1 --right-of eDP-1-1 --output DP-3.1 --right-of eDP-1-1 (I use both in a script) causes freezes and lockups. kscreen2 is disabled. The issue is more evident with a external monitor attached to the docking station, less evident when the external monitor is connected to the laptop port.

Ok. Can you check if 4.14.5 works? .6 had a change regarding i915 vsync timestamps, which shouldn't affect your system, but who knows. Other than that, you have the vgem drm driver enabled, maybe that's interfering. Are you running a custom kernel? The difference in behaviour between docked/direct connection would point to a hardware issue but then it's strange why this would only happen with Prime sync enabled.

Taken a look at your old logs from the kscreen2 flashing and the only noticeable change was the kernel, 4.14.4 at that time. Same xserver and nvidia driver.

I will check with 4.14.5, sure. I'm using a custom kernel, so if you think that some config change could help to understand what's going on, I can do that with no effort. And yes, but the flashing issue was solved by stopping to kscreen2, then after some kernel changes the issue with xrandr stepped in Thanks for the hints

With 4.14.5 the behaviour is quite similar, but not completely the same. basically it freezes but it takes more "actions" (windows dragged across screens and so on). But basically it is the same. The difference may be that in 4.14.5 I was not loading the firmware. On the same hardware (dual boot) windows manages the situation correctly.
