Confirmed, older versions work fine. The next problem is that a freshly compiled kernel (HEAD from today) panics with this: http://people.fsn.hu/~bra/freebsd/20090107-freebsd-x4540/Screenshot-55.png "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 strange. Maybe Peter can help? Thanks,
