The errors above can be ignored.

mlock(2)
mlock() locks pages in the address range starting at addr and continuing for len
bytes. All pages that contain a part of the specified address range are
guaranteed to be resident in RAM when the call returns successfully; the pages
are guaranteed to stay in RAM until later unlocked.

Can you post 'dmesg'? It might be a side effect of PAE Kernel also, but I'd
suggest using memtest for starter. How many RAM do you have? Have you tested it
before?

It's too difficult question, but I can tell that I had about a couple of dozen
1.4 based boxes and they worked correctly. If it's a HW problem you see it in
'dmesg' (at startup, when the kernel detects HW).
