4.19.42+ kernel broke the file system, LZ4 issue, how to revert to prev kernel?

[Nachteule]

Quote:Their website says that the btrfs with LZ4 compression support is there and it managed to read at least some of the files, so at least partially it worked. I don't know if all the files would've been recoverable. There could've been problems also somewhere else.

Sure, hard to say. And sd-card has been reflashed - so any further discussion about this is useless

But its interesting that rescue-cd supports lz4 compression. I couldn't find the info on their web-site, but I'm trusting you.

Today I was trying to reproduce what you did - I was wondering how it was possible to install newer kernel - and now I figured out what you probably did:

You run sudo xbian-compress and this command failed with error. But you did not reboot the system, you just returned to the command prompt. And at this state, information about the btrfs compression status was lost, because xbian-compress remounts root fs with lzo compression. And - unfortunately - the installation procedure checks current mount status of root fs only, nothing more.

So, finally, you was able to install kernel again

Quote:here seems to be some problems with the fresh install, the initial configuration wizard and the Kodi xbian config both freezing when loading the list of packages installed and to be installed. Oh well, I'll start another thread for that.

I was asking if your freezing issue is still there, not if your compression issue still exists
