This means the original version of the patch you found had a few problems, but they were all fixed later and only applied with CONFIG_PARAVIRT enabled anyways. As a stab in the dark since the CPU has clflush can you please comment out the if (cpu_has_clflush) asm("clflush (%0) " :: "r" (addr) : "memory"); statement in arch/i386/kernel/alternative.c and see if it makes a difference? Perhaps your CPU doesn't like that (it seems to have clflush) If that doesn't help it might be needed to revert the patch hunk by hunk to see which text_poke() invocation caused it. -Andi - 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/
