So there are only a few ways for users like me with RPi2/3 and DVBSky S960: staying at the "last" running build 8.0.2, changing the hardware or changing the distro (to a one with kernel <4.9). Or hoping for a kernel-patch. Right?

Changing the distro will not work because some new features (like improved HEVC support) require a new kernel.

Current master of LE 9.0 can still be built with an older kernel as long as you use this version of hevc optimizations patch and an older version of ffmpeg (3.3.2-30554d7).

I appreciate your work and am still using your build for RPi2, V 8.0.2. Any chance for a build for latest stable LibreELEC V 8.2.1? Thank you.

I built the 8.2.1 RPi2 image with kernel 4.8 but it doesn't work properly (HEVC doesn't work). The new version of ffmpeg HEVC patch is incompatible with older kernels. I tried to use an older version of ffmpeg HEVC patch but Kodi failed to build with it.

I tried the "no sdcard" method on my Pi3 and it works - I was able to boot LibreELEC from USB flash drive. However, it does not boot after a soft reboot. It requires a power cycle to boot. Any ideas if this is normal behavior?

Any chance of an x86 build of 8.2.0 with the old 4.8 kernel?

I'm not going to bother with 8.2. Here's an updated generic 9.0 Leia build with kernel 4.8.

LibreELEC-Generic.x86_64-9.0-devel-20171122224031-231122-k48.tar

That should work.

Looks like it's I/O dependent: the problem manifests after tens of minutes when just displaying DVB stream (cca 90mins) but with heavy disc I/O in serveral minutes...

I noticed that too.

Would you confirm that 4.8 would be the newest kernel not having the issue described here?

Yes.

So is this issue resolved?

No.

What was the commit that caused the problem?

Nobody knows for sure.

did this issue affect OSMC

Yes.

I would start with doing a test without the big RPi update patch

The RPi2 build fails with unpatched vanilla kernel. The only way to build without a RPi patch is to use a kernel from raspberrypi/linux git.

I decided to mess around with kernel 4.9.48 and replaced USB and PHY kernel driver sources with the sources from kernel 4.8.16 (I simply replaced drivers/usb and drivers/phy folders). I built an RPi2 image using that "modded" kernel. The issue is still there. So I guess it is not a USB issue and commit e6445f52d9c8b0e6557a45fa7d0e8e088d430a8c (The big USB, and PHY, and extcon, patchsets for 4.9-rc1) have nothing to do with the issue.

Any other ideas are welcome

We need someone who can reproduce the issue on a PC and a good linux skills. Otherwise this will never be fixed.

Building images with downgraded kernel becoming less useful, especially for Rpi2/3.

I can confirm no improvement with kernels 4.13 or 4.9.43.

Quote from polo_joe

Is this commit also in latest Milhouse testing builds with kernel 4.13?

Yes.

I'm unable to test this right now due to rainy weather (poor signal from my sat dish).

@HiassofT

I will test it ASAP.

VC1 1080p will not play smoothly on Pi2/3 without a license.

Try a LE8 image without media_build.

Isn't it supported via media_build?
