Hi,
I have a server with the following specs:
- Pentium G4600 CPU (with Intel 630 GPU)
- 16GB ECC RAM
- Supermicro X11SSH-F µATX board with IPMI
Software:
- Debian sid
- Linux kernel 4.14.17
- kbl_dmc_ver1_01.bin, kbl_guc_ver9_14.bin, kbl_guc_ver9_39.bin, kbl_huc_ver02_00_1810.bin in /lib/firmware/i915 (a warning in dmesg told me to add those)
- Docker 18.02.0-ce with runc 1.0.0-rc5
- tried both the official Plex and now the LinuxServer.io container
- Plex 1.12.0.4829
I added /dev/dri as a device and enabled hardware acceleration in the PMS settings.
It uses the GPU successfully, I can check that with intel_gpu_top in the main OS.
Transcoding a 1080p h264 or a 4K HEVC movie for an iOS device works fine.
But when I use Safari on my Mac and start something to transcode, the entire machine freezes and I get this in the serial console (via the IPMI interface of my server board):
Disabling lock debugging due to kernel taint

I don’t know how to proceed debugging this, so I have started here in the Plex forums.
Has anyone an idea what can cause this?
Kind regards
