Sorry, I had removed OpenBSD from the hard disk due to the shutdown problems. Here are the dmesg, pcidump -v and atactl sd0 identify from a UBS stick installation. I had tried both i386 and AMD64 on the hard drive with the same shutdown result. I have the latest BIOS, verified from Acer's web site.

Hi all,

I've got a strange situation with OpenBSD 4.9 on a new laptop, an Acer
Aspire 1430 with an Hitachi 500 GB SATA disk, model HTS545050B9A300.
When shutting down, OpenBSD does not spin down the disk, resulting in an
"emergency unload" according to Smart terminology. Until I can resolve
this issue, I've uninstalled OpenBSD from it, since smartctl reports in
Slackware that there have been 17 "Power-off Retract" events so far,
which could damage the disk in the long run. However I would really love
to run OpenBSD on my laptop for the simple reason that I love it so much
more than Linux.

Can anyone suggest what I could do to stop this from happening? I found
a discussion on a FreeBSD mailing list identifying and trying to resolve
the exact same thing through kernel recompilations:

http://freebsd.1045724.n5.nabble.com/Re-Spin-down-HDD-after-disk-sync-or-before-power-off-td4043068.html

However, neither using FreeBSD nor patching the OpenBSD kernel would be
a preferred choice for me. I'm sure there must be a simpler solution,
maybe a sysctl setting I'm over-looking...? I've tried both IDE and AHCI
modes in the BIOS with the same results.

Thanks,

Steve Schaller
