That can be indeed a bug in the BIOS. Disabling HT capabilities should not make the "pae" flag to be exposed in the OS :-? >> Something seems seriously broken with your machine and PAE (HT/PAE >> combo), dunno what nor why because your system looks PAE-aware and >> capable :-? > > I have since discovered a couple of other people who have the same > problem...all on machines using older (circa 2002) Intel boards and > cpu's. (...) Then you better disable HT and use a "non-pae" kernel until someone can provide more data on why/how the error is triggered. What happens with a pae kernel of another distribution? Or with an own-complied kernel? Are you experiencing the same? If "no", this can be a start point to further debug the problem. If "yes"... well, time to upgrade that motherboard or live with a 486 kernel O:-) Greetings, -- Camaleón -- To UNSUBSCRIBE, email to debian-user-requ...@lists.debian.org with a subject of "unsubscribe".
