system_powerdown and OpenBSD 4.8

Hi all!

Does system_powedown work with OpenBSD 4.8? When I run this command from
Qemu Monitor, the VM freezes using both bsd and bsd.mp stock kernel.

Thanks in advance for your replies.

Regards,
Daniel

I forgot to mention that the VMHost is Debian GNU/Linux Lenny with Linux
2.6.34.5 manually compiled with the kernel.org source code and qemu-kvm
0.12.4 from Backports repositories.

Fwiw, that version of qemu-kvm does not have a fix for system_powerdown,
this one:

 http://git.debian.org/?p=collab-maint/qemu-kvm.git;a=commitdiff;h=e05434807329e1ee0c03090e61f37bce8f2f74c0;hp=2c9b9525f8d0eff259117ca033b7522118877eaf

which went into one of the latest squeeze qemu-kvm releases,
and which is also available on bpo.

I just upgraded to 0.12.5 qemu-kvm from Backports repositories. I turn
off the virtual machine, then I boot it and I tried again with
system_powerdown from Qemu Monitor, but I get the same result: the VM
freezes when running the command.

As I was reading in the comments of the patch, it was due to problems with
system_powerdown with FreeBSD.

Maybe OpenBSD behaves differently. Is there some debug command that I
can use to provide more data?


Thanks for your reply.

Daniel

Yes, as far as I remember OpenBSD completely freaks out when it gets SCI
interrupt. I was not able to find out why. Does it work on physical HW?
