The new 4.3 kernel is ready.
deb http://apt.osmc.tv jessie main to deb http:/apt.osmc.tv jessie-devel main
sudo apt-get update
sudo apt-get install rbp1-kernel-osmc or sudo apt-get install rbp2-kernel-osmc
sorry for the delay, I will do test it in the weekend.
I noticed also that kodi does not connect to mysql. I see in the forums that it should have “wait for network” enabled to get connected to mysql.
Can I enable “wait for network” without connman?
Thanks!
Not reliably but your network should be up if you booted from it. Kernel (4.3) is experimental at the moment, so exercise caution.
Sam
Is there a way to enable “wait for network” outside the UI. I cannot exit the UI for some reason. The only way to get out of MyOSMC is to exit kodi or reboot.
Hi
The new kernel should be ready to try now so let me know.
Your comment about My OSMC is interesting and is possibly caused by the Network Code. Can you get a Kodi debug log of that?
Thanks
Sam
The wait for network option the GUI just does:
sudo systemctl enable connman-wait-for-network.service
However if you are not using connman this service will not do you much good without modifying it to check network connectivity some other way.
However if you are on an NFS root install you shouldn’t need to do anything as the network will already be connected.

Somehow it managed to install it (I did an apt-get dist-upgrade it found the incomplete installation and finished it). However it does not boot. It stays at the rainbow screen forever.
You have installed a Pi 1 kernel on your system. The instructions above were not clear, but you were meant to install rbp1-kernel-osmc or rbp2-kernel-osmc depending on your device.
The good news is this is revertible. Insert the SD card, rename kernel.img to kernel.img.old and rename the latest vmlinuz file before 4.3 to kernel.img and your device should boot again.
We are currently experimenting with initramfs which may cause some kernel breakage at the moment, so please exercise caution.
Sam
Don’t want to open a new thread since I was aware that adding jessie-devel to the apt sources involves risks, I just want to highlight that the latest kernel update broke both my raspis (1 B and 2 - both not able to reboot due to kernel panics). Furthermore, the one before the last one (or one before that, not sure) broke the connection of my wifi dongle (tp link 821n - I guess http://jenkins.osmc.tv/job/rbp1-kernel-osmc/52/changes#23812c14ea935844c14058817a5963b8de87b0b0 or http://jenkins.osmc.tv/job/rbp1-kernel-osmc/51/changes#015793627f588bf64657dc63eb1af55a2bb332c8 caused it, maybe somebody can cofirm).
Thanks again for your efforts, Sam & the team.
If you installed this from the testing repository, then this is not an issue per se. Breakage is expected in this repository. Simply rename an older vmlinuz on /boot to boot again.
Sam
I know Sam, it’s more of a question of what would be the best way to highlight it when something breaks from the testing repository.
There isn’t as far as I know, which is why we call it testing. It would be exhaustive for us to mark what is and isn’t broken, and difficult. Packages go straight in to testing straight after compilation, so we would not be able to confirm things on a package by package basis
Hi again,
it seems with kernel 4.4.1-1-osmc the issue (hw csum failure) is still here.
It seems to happen only when the ethernet is bridged with another interface. I have another rpi2 running exactly the same OSMC, but its eth0 is not bridged, without any issues.

For some reason ipv6_mc_check_mld and ipv6_mc_validate_checksum are still called.
ifconfig shows no ipv6:

ipv6 is not disabled at the kernel driver level in OSMC.
It is only disabled by default in connman when new interfaces are created/configured, which means no ipv6 address is allocated. You can still enable ipv6 on an interface using connmanctl.
Can be disabled somehow?
I see ipv6 module is loaded:
