does it? I was pretty sure that a !NUMAQ i386 CONFIG_NUMA build already used that. At least that was the case when I last looked. If that has changed it must have bitrotted recently. > or two and > enabling BOOT_IOREMAP.

That was always the case If it crashed on a (older) Summit then it likely bitrotted, because that worked at some point. The code was originally written by Pat G. for Summit1 and I believe was at least used by some people (no distributions) for S2, possible 3 too. > Ok, understood.

Again the problem shouldn't be normal machines, but non Summit NUMA systems. -Andi -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
