Description Axel Fontaine 2015-12-09 15:47:18 UTC 
Busybox worked great until 1.22.1 for Linux guests within VirtualBox.

Starting with 1.23 up to the current version (1.24.1) ACPI Shutdown from the VirtualBox UI stopped working. Reverting to Busybox 1.22.1 with no other changes makes it work again.

All versions were built from source based on the same 1.22.1 config.

Setup: Busybox init is started by the kernel and starts a shell script (referred to in the sysinit section of inittab) that calls acpid -d

By stopped working I meant: has no effect anymore, the instance keeps running instead of shutting down as expected
Comment 2 Mike Frysinger 2015-12-09 17:22:21 UTC 
you probably need to trace this a bit for us to see what command is changing in behavior

if you don't mind using git, the bisect operator might help speed things up

This is the only recent commit to halt.c after 4 years: https://git.busybox.net/busybox/commit/init/halt.c?id=86a7f18f211af1abda5c855d2674b0fcb53de524

Could that be the cause?
Comment 4 Axel Fontaine 2015-12-09 17:35:22 UTC 
The only other suspect could be:
https://git.busybox.net/busybox/commit/init/init.c?id=da9212667c99f2f2121747c4715d067deb7c155b

Not much else happened within https://git.busybox.net/busybox/tree/init in the affected timeframe
Comment 6 Mike Frysinger 2015-12-09 21:43:47 UTC 
you have the system that's failing, so it should be pretty easy to test each one of those commits to see if they fix your system, and then you can let us know

This issue may be similar to Bug 12071, which may be caused by

In addition, someone reported it in busybox github mirror:
