The CONFIG_IA32_EMULATION option is for a 64-bit [ x86_64 ] kernel, to enable it to run 32-bit userspace (either only 32bit userspace, or multilib). So, it is irrelevant for a 32-bit kernel - those can only run 32-bit userspace. If your previous "good" kernel was either 32-bit or 32-bit with PAE, you might need to change a lot of .config settings to get a reliably working 64-bit kernel. And vice-versa for a well-adapted 32-bit kernel if you had previously been running 64-bit. Your main problem appears to be that part of kde is unusable, and you attribute this to the old firmware. That may well be true (I don't use kde), but I will be very surprised if that is the _expected_ result of running the old firmware on an early phenom. Usually, running old firmware doesn't seem to make a lot of difference, except in obscure corner cases. I will note that my own phenom *sometimes* seems to lose its lunch when running make -j4, and in those cases dropping the caches and running a less-adventurous parallel make [ -j3 or -j2 ] seems to fix it. But that doesn't seem to be analagous to the kde problem you see (and when I last looked, a few months ago, my firmware appeared to be current, so I guess mine is the common "cheap consumer hardware" sort of problem). Anyway, best of luck and I hope you get it sorted. Perhaps I should also upset you by mentioning that 3.8 seems to be out of maintenance (except, probably, from ubuntu). In general, the devs here aren't too interested in old kernels which are no longer supported. OTOH, I'm reluctant to suggest what I would normally suggest in the "distro" (LFS) I care about - i.e. try both 3.12.0 and 3.12.latest, both from a known good .config using 'make oldconfig' - because you are starting from an old version and it isn't obvious where the problem started. Those of us with specific requirements really need to keep checking each kernel release (or ideally some of the later -rc versions) to make sure that things we care about haven't been trashed. ĸen -- das eine Mal als Tragödie, dieses Mal als Farce -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
