Comment 50 for bug 1749086

1) It's pretty much hit and miss at this point, sometimes takes longer sometimes shorter, 5 minutes is still not out of the question but most of the time it boots ok, although a new error started appearing: [ 3.292085] usb 1-3.5.1: device descriptor read/64, error -32

2a,b,c) I've been using Kubuntu 14.04 for years without any problems. The problems started recently, when I upgraded to 16.04.(maybe I should consider downgrading kernel?) Never encountered any serious problems on this hardware in any distro/version prior to 16.04 (as I mentioned earlier, current kernel misbehaves in Xubuntu, Kubuntu and OpenSUSE)

2d) nothing out of ordinary, a minute or so (guess)
3) attached (as you will find on this occasion boot up was quick but it's not always the case)

Tomorrow I will have time to test it more thoroughly to observe how frequently abnormalities appear.
