    Default kernel 2.6.25.18 or 2.6.25.5 for openSUSE 11.0 ?

    Hi,
    The kernel that my openSUSE 11.0 has is 2.6.25.18-pae. In webpin i see that kernel 2.6.25.5 is also available. Which is the latest version? If 2.6.25.5 is the latest, will it cause problems if i decide to upgrade to it?

    And what is kernet-rt, the realtime linux kernel?

    18 > 5 so you already have the latest.

    And now i feel sheepish. I assumed that 2.6.25.5 was a different 'series', but then webpin also has 2.6.25.9 => my brainbox was not working too well.

    I thought that motherboards for 32 bit processors did not have more than 4GB memory support, so why one needs PAE support ?

    Some do. Why -pae gets installed in some cases I don't know. I have this 400 MHz Celeron with only 256MB but the installer picked -pae. The processor is capable of PAE, that extension goes back a long way, but anything approaching 4GB on this motherboard is simply dreaming.

    Is there any talk of the Linux kernel not being made for 32 bit processors sometime in the near future? Cos i have a P4 and everyone now buys dual cores or quad cores or amd's 64 bit ones.

    No, why should they? Lots of computers in the world still run 32-bit. Netbooks for example, which is a fast growing area.

    The number of cores is not correlated with 32 or 64 bit.

    This makes me

    Ja, but i thought that Intel's multi-core desktop processors were 64-bit.

    anyways, what i needed to know about Linux supporting 32-bit kernels, i know now. Thanks.

    There are still quite a few multicore 32-bit processors also. There has been talk about the possibility of fabricating lots (hundreds, thousands) of the basic original Pentium core on one chip for multiprocessing.

    Supporting multiple architectures in Linux isn't that hard. The vast majority of the kernel code is architecture independent. Only a small number of lines have to be specific to the architecture. Since the x86_64 arch has as a subset the i386 arch, that is another reason you can expect the i386 arch to be supported well into the foreseeable future.
