Dear GRUB developers,
on the ASRock E350M1 with coreboot, running the GRUB 2 payload and
loading the module `halt` and executing `halt`, the system reboots
instead of halting. The GRUB 2 revision includes the latest DSDT parser
fixes(?), as before `halt` returned that the machine is not supported.

Please find the DSDT extracted with
$ sudo acpidump --table DSDT --output asrock-e350m1.dstd
attached.
Doing `halt -p` or `poweroff` from Debian Sid/unstable (Linux) works
without problems. (Note that I was told, that just `halt` should
actually not power off the system and that this is a SysV bug [1].)
Thanks,
Paul
