I thought that I did testing with an older version, but as it turned out
I was wrong.
Confirmed, older versions work fine.
The next problem is that a freshly compiled kernel (HEAD from today)
panics with this:
"BIOS smap did not include a basemem segment!"
which is true, according to the above verbose output and taking a quick
look at the code. (in the loop there is only a base=0x0 and len=0x0 entry)
I'm not an expert of this topic (too), for me these numbers look pretty
Maybe Peter can help?
