This patch fixes it for x86-64 and powerpc-64. On the other 64 bit processors iotop works but instead you get a message in dmesg: kernel unaligned access to 0xe000023879dca9bc, ip=0xa000000100133d10 So on those arches you were already getting posts to bugzilla etc. Now those people can upgrade the kernel and download iotop version 0.4.2 or higher. regards, dan carpenter -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
