Dear Pavel and Dave, > The assertion was that 4GB with no PAE passed a forkbomb test (ooming) > while 4GB of RAM with PAE hung, thus _PAE_ is broken. Yes, PAE is broken. Still, maybe the above needs slight correction: non-PAE HIGHMEM4G passed the "sleep test": no OOM, nothing unexpected; whereas PAE OOMed then hung (tested with various RAM from 3GB to 64GB). The feeling I get is that amd64 is proposed as a drop-in replacement for PAE, that support and development of PAE is gone, that PAE is dead.
