AT THIS POINT IT WORKED !
But not automatically though ?! I have to manually put in the hint.
Hm, so something clears the flag again (or prevents the flag working). Could you try to figure out when and where no_multi_io flag is set and cleared, e.g. by adding printk()s in the code path?
So it looks like things stalled a bit here; if you still need info from someone with an affected system I can try and do it, but you might need to walk me through it / provide patches a bit more than the above, as I'm just a dumb qa monkey :) If you can make it a bit more 'tab a, slot b' I'll try and do the testing. Thanks!
