[SOLVED] vlc / driver cause crash after waking from suspend state ?

Hello, i'm linux newbie, don't know where to ask.

Problem: when i play video with vlc which uses the libva, it works, but when i then suspend pc and after waking try again, pc crashes.
When i suspend without firstly using libva it all works as in "bootup session", so basically the condition is to use libva and suspend to trigger crash.
Actually i'm not sure if its caused by libva, just suspect it is, cant locate any related log info, journal and xorg seems to not register this event.
Can someone please hint where to find this kind of log ? Driver debug log or something like that ?

Is there anything i can do ?

As far as i know everything is up to date.

Running on Arch + plasma + xorg.

My GPU: Radeon HD 7850

Drivers used from package: libva-mesa-driver

Here is vainfo:

libva info: VA-API version 1.14.0
libva info: Trying to open /usr/lib/dri/radeonsi_drv_video.so
libva info: Found init function __vaDriverInit_1_13
libva info: va_openDriver() returns 0
vainfo: VA-API version: 1.14 (libva 2.13.0)
vainfo: Driver version: Mesa Gallium driver 21.3.3 for AMD PITCAIRN (DRM 2.50.0, 5.15.13-arch1-1, LLVM 13.0.0)
vainfo: Supported profile and entrypoints

      VAProfileVC1Main                : VAEntrypointVLD
      VAProfileVC1Advanced            : VAEntrypointVLD
      VAProfileH264ConstrainedBaseline: VAEntrypointVLD
      VAProfileH264ConstrainedBaseline: VAEntrypointEncSlice
      VAProfileH264Main               : VAEntrypointVLD
      VAProfileH264Main               : VAEntrypointEncSlice
      VAProfileH264High               : VAEntrypointVLD
      VAProfileH264High               : VAEntrypointEncSlice
      VAProfileNone                   : VAEntrypointVideoProc

When i run vlc with verbose flag and play video i see this:

[00007f6c14006440] gl gl: Initialized libplacebo v4.157.0 (API v157)
libva info: VA-API version 1.14.0
libva info: Trying to open /usr/lib/dri/radeonsi_drv_video.so
libva info: Found init function __vaDriverInit_1_13
libva info: va_openDriver() returns 0
[00007f6c28c34570] avcodec decoder: Using Mesa Gallium driver 21.3.3 for AMD PITCAIRN (DRM 2.50.0, 5.15.13-arch1-1, LLVM 13.0.0) for hardware decoding

But after the suspend and trying again last line showed is: "libva info: va_openDriver() returns 0" so "avcodec decoder" or something in between must somehow trigger the crash.

Also ffplay is not affected by this issue, guess thats because it doesn't use libva.

Edit:
I tryed to uninstall libva-mesa-driver, which means its not actually issue with the specific driver itself, because problem persist.
This time vlc -v shows this:

[00007fe2d4006440] gl gl: Initialized libplacebo v4.157.0 (API v157)

After suspending and trying again last line showed is: "vaapi_filters filter warning: Using SW chroma filter for 1920x1088 VAOP -> I420"

Re: [SOLVED] vlc / driver cause crash after waking from suspend state ?

Figure it out !
VGA kernel driver in use was wrong, was using radeon drivers instead amdgpu once whole time, that caused this issue.
Just following the Arch Wiki page solved it
