The story is that 4be2c95d1f "taskstats: pad taskstats netlink response for aligment issues on ia64" broke iotop on 64 bit processors (32 bit was unaffected). 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.
