I'm not Patrik, but I saw this on two Intel boxes running on 6.2. smbios.system.product="S5000PAL". I didn't try the later releases on them.

I wouldn't mind adding non-Apple hardware to this list, but only if you can tell me the following:

There are many Intel ICH boards with this "feature", not just Apple Macs. ;-)

I heard disabling legacy keyboard/mouse emulation may work around the problem if there is option in the BIOS:

The hack for Mac is required because it doesn't have "BIOS".

FYI, I found RT Linux people wrote a simple tool to control the bits from user space:

I found I had a similar (but very old) tool for FreeBSD:

Originally it was posted here:

It was a different symptom but basically the same problem, i.e., a buggy BIOS spinning too much time in SMM code.
