--- Comment #14 from Anthony Williams <anth...@adfw.co.uk> --- My T400 has 8GB memory (2x4GB). I've just tried it with 1x4GB, and it has the same problem as before. I don't think I have any smaller DDR3 SODIMMS to hand at the moment. However, if I set hw.physmem at the loader prompt, I get some interesting results! All with 8GB installed: hw.physmem="2G" -- boots 12-STABLE with SMP hw.physmem="4G" -- boots 12-STABLE with SMP hw.physmem - not set -- fails during boot Henrich, perhaps you could confirm that you can alter the behaviour by setting hw.physmem as well (hopefully it saves you the trouble of moving physical memory around also!) -- You are receiving this mail because: You are the assignee for the bug.
