Good we have a fix for a bug, that has been pestering me for quite a long time. As for maximum timeout, I believe that setting a maximum timeout in sysfs with d

  50ms should be quite enough i think. That's 5X the minimum, more than any proper device should ask for. If you want to be extreme you can make it 100ms but any more than that is way to extreme.

    "50ms should be quite enough i think" If you are going to make a statement like that, make it "64ms ought to be enough for anyone". Either way, it won't help. If you write kernel code or interface with unknown hardware, you must be paranoid to the bone to get robust code. Double so if your kernel code talks with hardware you do not control. "more than any proper device should ask for." If devices asked for time, things would be easy; you either reply 'no', or you give them the time they ask for. The problem is that they take time without telling you.

      Well given that 90% of hardware out there is supported just file with the current setting i suspect 50ms would qualify as quite paranoid.
