Re: i915 Skylake GPU hangs with kernel 5.3.11

Now that linux 5.5.1 is out of testing is anyone able to reproduce the issue?

I'm still getting it here. Computer freezes whenever I do anything beyond a TTY. Only way out is to use the power button (tapping it *does* work to do a normal shutdown sequence).

Re: i915 Skylake GPU hangs with kernel 5.3.11

@DarrionOakenbow as you can shutdown normally I would expect the journal to be saved to disk.
What is the contents of the journal from a boot with the issue under 5.5.1?

Re: i915 Skylake GPU hangs with kernel 5.3.11

My data point: I had complete freezes every 30 minutes on one of my desktops, where I had to do a hard reboot every time it happened. After installing kernel 5.5 from testing earlier today and using the kernel boot parameters `intel_idle.max_cstate=1 i915.enable_dc=0` I was able to work for 4 straight hours (and it didn't crash yet). I didn't try just upgrading the kernel without the params, so not sure if both are strictly necessary.

I just updated earlier today and have been running smooth since then (i9-9900 /  Intel UHD Graphics 630 using modesetting). See post #82  for ref on what I was seeing.

Spoke too soon. Although the issue feels the same (frozen screen, only reboot will cure), I can't verify as there was no info in the systemd log like before. Moving back go 11/17 again.

Working well here. Both the linux-5.5.1 and linux-5.5.2 kernels. Also works on zen. Reenabled hw acceleraion on opera. Custom linux and linux-zen kernels also running fine.

No i915 specific kernel parameters used, but using this for months now:
[...] nowatchdog scsi_mod.use_blk_mq=0 libata.noacpi=1 consoleblank=300 drm.edid_firmware=edid/edid.bin pti=off spectre_v2=off l1tf=off nospec_store_bypass_disable no_stf_barrier [...]

During this issue, switched over to using sway... Now I'm not willing to go back to xfce/lxde/fluxbox to do testing there...

Re: i915 Skylake GPU hangs with kernel 5.3.11

I have similar observation as tpfkanep. Running 5.5.2-arch1-1 with ~2 days of uptime and I have no issues do far. Also, I'm not using any i915 related kernel flags, all default. The problem seems resolved, at least for my machine. smile

Off topic but, you can just use "mitigations=off" parameter instead of all those spectre, l1tf etc. lines.

Re: i915 Skylake GPU hangs with kernel 5.3.11

My desktop froze several times today. I have experienced these freezes for several weeks now when using Firefox (currently 73.0). With the latest kernel update the freezes seem slightly different in character (sometimes the desktop unfreezes after some waiting), but today they were more frequent. Twice today I was kicked out of the xfce4 desktop and had to login again.

Running kernel 5.5.2 on a ASrock N3700-ITX motherboard with an Intel N3700 SoC. I chose for this motherboard/processor because of its low energy consumption and it has worked fine for me until a few weeks ago.

Re: i915 Skylake GPU hangs with kernel 5.3.11

Doing fluxbox testing. Smooth sailing so far. +- Six hours. Went so far as running fluxbox on one tty and sway in another. Browsers, video decoding/encoding. All running simultaneously. So far so good. On latest linux 5.5.2.arch2-2 kernel and zen. Both modified kernels.

Re: i915 Skylake GPU hangs with kernel 5.3.11

Would like to add that i am still having problems with i915 on 5.4.x and 5.5.x.
When i run 5.3.13 there are no problems whatsoever.

Feb 11 17:13:44 KiloBit kernel: i915 0000:00:02.0: Resetting rcs0 for preemption time out

Feb 11 17:13:54 KiloBit kernel: Asynchronous wait on fence i915:picom[1475]:3f70 timed out (hint:intel_atomic_commit_ready+0x0/0x50 [i915])

Device:
Listed in signature
Kernel options:

I have set GUC from 2 to 0 to troubleshoot, still hangs.

When the hang happens i have about 10 seconds to switch to a different TTY. If i do that i can successfully shutdown the system after waiting for a while. If i wait longer on the original TTY after hang then the laptop becomes completely unresponsive.

Re: i915 Skylake GPU hangs with kernel 5.3.11

It now drains a lot of battery even with RC6 enable.
Proper TLP configuration is needed on laptop : CPU and iGPU frequency.

Any idea why on a MSI PS63 wifi card could drain 8W !!!! that's crazy

Re: i915 Skylake GPU hangs with kernel 5.3.11

still problems on 5.5 - some of the critical patches from drm-tip never made it upstream to 5.5.

@alu1 does adding those two commits or drm-tip resolve the issue on your system?

Re: i915 Skylake GPU hangs with kernel 5.3.11

linux-lts package moved to 5.4.x LTS and now I am facing again this problem in the LTS and current kernel.  I need to main in 4.x kernel to avoid this issue....

archive repo's will help if you don't have it in cache ! Better to stay in kernel < 4.19.85 to have RC6 enabled

RC6 is something worth downgrading to < 4.19.85? I am running 4.19.101-2. It is a PC not a laptop.

For sure they disable it since 4.19.85 ... as a security issue. They patched it in since 5.5.2 but i seems yo have different behaviour
It will have more power consumption it doesn't really matter except few bucks more on your electricity bill ...

it is my work PC at my job, so I think I can live with that smile (what it is really annoying is to have the screen frozen everytime with 5.x kernels)

@alu1 does adding those two commits or drm-tip resolve the issue on your system?

it took over a week for the problem to manifest in 5.5. i've been running drm-tip for a day without issues, yet.  i'm finding it dificult to keep on top of which patches they want applying where with all the movement in their codebase, so will stick to my current snap of drm-tip.

5.5.3-arch1 added https://git.archlinux.org/linux.git/com … b3cc0f4d52 which may help those still experiencing rcs0 issues on 5.5


5.5.3 made my system  quite a lot more stable. Although i  still have had two i915 related crashes. log:
