Hi.
I've now tested GENERIC and GENERIC.MP on amd64 with bigmem enabled.
src/sys was updated yesterday from CVS. With bigmem=0 both GENERIC [1]
and GENERIC.MP [4] works fine (I am using GENERIC.MP on a daily basis).
With bigmem=1 and the BIOS "Memory Remap Feature" _disabled_, both
GENERIC and GENERIC.MP seems to work. It is only showing 3GB, however.
With bigmem=1 and the BIOS "Memory Remap Feature" _enabled_, both
GENERIC [2] and GENERIC.MP [5] fails to boot (sorry for the crappy
quality; the only camera available to me was that on my mobile phone):

(GENERIC.MP shows this as the last 5 lines):

Next I tried to disable uhci (UKC> disable uhci) and was able to boot
and save the dmesg for both GENERIC [3] and GENERIC.MP [6]. Here's what
appears at the end of the dmesgs:

Below are the URLs to the various dmesgs and pictures. Please let me know
if there's anything else I can do to help.
