Hmm. Strange. I cannot relate that to what I was doing at that point in 
the installation.

Ah, hang on (imagine me waking up; should maybe have breakfast first...).

We also collect info for a hardware summary at that point. It could well 
be that one of the commands there caused it. ... And that does indeed 
include a cat of /proc/iomem and /proc/ioports.

Now for the difficult part: how do we find out which driver this was?

I'll see if I can reproduce while keeping a watch on loaded mods.

Cheers,
