Hello!
Since 4.19.17, I'm facing problems during streaming of videos I've never seen
before. This means:
- video from internet stutters although enough data flow can be seen in bmon.
- gpu is locked:
radeon 0000:0a:00.0: ring 0 stalled for more than 14084msec
radeon 0000:0a:00.0: GPU lockup (current fence id 0x0000000000053ed7 last
fence id 0x0000000000053f0f on ring 0)
- The connection of videos streamed locally by the machine for a TV suddenly
breaks (upnp - serviio as server).
After very long time of testing, I detected, that removing the complete patch
series for 4.19.17 regarding netfilter: nf_conncount makes the problem
disappear.
Please remove / fix this patchset!
Thanks
Andreas Hartmann
