I'm in doubt in this matter, because it's been absolutely stable so far and is as stable as before under Linux and XP. Also, my problems very much coincidence with some list traffic about the same problem, follow the thread: Subject: Seeing system-lockups on recent current Message-ID: I also managed to panic the system after repeated attempts to get through the installworld (which all failed). The panic string is "panic: pmap_enter: attempted pmap_enter on 4MB page" and is also described by the message: Subject: panic: pmap_enter: attempted pmap_enter on 4MB page Message-ID: <20031009130922.GI4970@wombat.fafoe.narf.at> I have debug kernel, but the system locked up after the message and I had to drive home and reset the system. All those problematic systems seem to be AMD based. -- Vallo Kallaste
