The motherboard is: smbios.planar.maker="MICRO-STAR INTERANTIONAL CO.,LTD" smbios.planar.product="MS-7368" mbios.bios.reldate="10/31/2007" smbios.bios.version="V1.5B2" I've been trying to find a solution for this for some months, but so far i've been unable to find anything. This problem is poping up in the lists every few months. I tried asking for help on how to debug this at least twice but i didn't get much help with it. Looking at the archives this is the most interesting things i could find: http://lists.freebsd.org/pipermail/freebsd-acpi/2008-September/005127.html and http://unix.derkeiler.com/Mailing-Lists/FreeBSD/current/2003-09/0574.html The former seems to be totally related and suggests using KTR to debug it. The second have some info about how did Bruce Evans debug some ATA interrupt problems. I don't know if it could be related or not, but at least gives me some ideas on what to look at when debugging it. If anyone have any idea on how could i debug this or patches to test i can try them.
