[Halium 9 Kernel Patching][GSI] Ubports fails to boot

flohack

Okay so do the following:

Boot to recovery
mkdir /a
mount /data/rootfs.img /a
cd /a/etc/init
vi /etc/init/lxc-android-config.override
place only one word inside this file: manual
sync
cd /
umount /a

Now, if you reboot, lxc startup will be disabled, you should be able to log in with ssh. Then you can execute lxc-checkconfig in the shell.

I managed to login but it asked me for a password. I used phablet and it looks like is accepted. But it get's stuck after that, and I can't do anything. After a few seconds the phone reboots. The file you mentioned wasn't empty, I removed everything and only placed manual in it

@Flohack https://del.dog/ofipomemed here's the last_kmsg log

nitanmarcel

It might be the hwservicemanager. I'm applying a patch rn

nitanmarcel

@Flohack Same story. I can ssh but as soon as I enter the pasword phablet the console tab freezes and the phone reboots after a few seconds. This time without any last_kmsg. Screenshot from 2020-07-13 16-48-09.png

I managed to get an last_kmsg after a few attemps: https://paste.ubuntu.com/p/gdThm8JyfF/

If I'm not wrong I think this is what crashes it.

35>[   36.966464,5] systemd-logind[3823]: Failed to start user service, ignoring: Unknown unit: user@32011.service

flohack

@nitanmarcel No that one you can ignore, its normal ^^

flohack

@nitanmarcel Please mount your rootfs again as described above and move out all startup jobs called lxc-* to another folder. We must prevent any interaction with cgroups and lxc. And we need to get the output of lxc-checkconfig (its not a file, rather you call this on the console)

nitanmarcel

@Flohack Same thing happens. I get stuck after I enter the password. I've also tried from recovery and the same thing happens.

nitanmarcel

Also after I connect with ssh and it freezes if I try from another tab I can't connect anymore

flohack

But does it bootloop?

flohack

Can you try this fix:
mkdir /a
mount /data/rootfs.img /a
echo manual |tee /a/etc/init/rsyslog.override
umount /a
sync
we disable syslog daemon for a while, see if that unblocks ssh

nitanmarcel

@Flohack Yes, it goes to bootloop again. I've tried your fix but it still get's stuck after I enter my password and the same thing happens as before with lxc. The phone reboot then goes into a bootloop as soon as the phone starts

nitanmarcel

And yeah, if I don't ssh the phone doesn't reboot. It just stays at the Android One logo

[Edit: then it shuts down]

nitanmarcel

I also tried with telnet

nitanmarcel@nitanmarcel:~/adb/Ubports$ telnet 10.15.19.82
Trying 10.15.19.82...
telnet: Unable to connect to remote host: Connection refused

flohack

Sorry out of ideas

nitanmarcel

@Flohack No problem, thanks for trying to help I've also tried to change my system from f2fs to ext4 and the phone didn't rebooted again, but I still can't ssh.

nitanmarcel

@Flohack I got an idea. Instead of using ssh can't we just make a script to run the command at boot and then store it to a file? like lxc-checkconfig >> /home/phablet/lxc-checkconfig

flohack

@nitanmarcel Sure you can craft a one-time upstart job in /etc/init. Go for it
