So which one, your patch or Hughs? This was an effect of me suggesting to switch off CONFIG_SLUB_DEBUG. If you did not run without CONFIG_SLUB_DEBUG then you were not affected by the problem. And the earlier case that you reported was a version of SLUB that did not have the capability to switch off SLUB_DEBUG. Is there any way we can boot with "slub_debug" on the kernel command line and get early printk output? Looks like an early failure that may have to do with other kernel debug options being on (lockdep or so?) - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
