Describe the bug

After flashing a simple module that just overwrites /system/etc/hosts and rebooting, adb is not working anymore. The device simply does not show up anymore, no matter what I try.

Deleting /data/adb/ksu/modules.img via termux and rebooting fixes the issue. In termux I can also see that /system/etc/hosts does get correctly replaced / over-mounted.

One thing that looks suspicious to me:

[   18.812591] [pid:1,cpu0,init]init: Service 'exec 5 (/data/adb/ksud)' (pid 701) exited with status 0 waiting took 0.150053 seconds
[   18.812652] [pid:1,cpu0,init]init: Wait for exec took 0.150207 seconds
[   18.814117] [pid:1,cpu0,init]init: processing action (sys.usb.config=hisuite,mtp,mass_storage,adb && sys.usb.configfs=1)
[   18.814331] [pid:1,cpu0,init]init: write_file: Unable to write to '/config/usb_gadget/g1/UDC': No such device
[   18.814727] [pid:1,cpu0,init]init: Service 'macaddr' (pid 693) exited with status 0
[   18.815124] [pid:1,cpu0,init]init: cannot find '/sbin/adbd', disabling 'adbd': No such file or directory

In dmesg.log.old, cannot find '/sbin/adbd', disabling 'adbd' does not appear.

I know this kernel is quite old, and it could be a weird kernel bug. So I don't expect anyone to spend much time with this. Just wanted to ask in case someone as an idea. Thank you!
