overlay_remounter: umount FAILED: /system: Device or resource busy

[Anonymous941]

Device: fogo
Android version: LineageOS 16
Magisk version name: v30.7
Magisk version code: 30700

I am experiencing a bootloop after upgrading to the latest LineageOS version. It reboots immediately, before the LineageOS logo even shows. It worked previously, and disabling the modules doesn't help.

Unfortunately I cannot attach last_kmsg as compiling my own kernel also causes a bootloop (without even installing Magisk) even if I use the exact same config that LineageOS does. I am only able to get logs through /sys/fs/pstore/console-ramoops-0, except those logs are corrupted.

Each boot, it says overlay_remounter: umount FAILED: /system: Device or resource busy five times and then init exits, causing a kernel panic. I tried modifying the source code:

 }

But nothing changes. In fact, Magisk logs absolutely nothing throughout the whole boot process. It's like it's not even replacing init.
