I think it was around Fedora 18? kernel time frame.. on certain Lenovo T440? if you did a dd to a usb key, keyboard and mouse would be like you pointed out. In fact any hardware actions on the same bus would be 'funny'. My fuzzy memory for the reason is that the usb stick and keyboard/mouse are generally on the same USB hub, and communication competes on a hub for what happens. The kernel and hardware have to come to some sort of agreement not to flood the bus but something in that kernel to improve some other performance turned off that agreement. So if you did a lot of disk io on certain hardware it would cause a lockup/spew. I fixed my problem by accident when I got a laptop refresh which had a different USB controller. Same kernel, same action, no problem. I think in general the problem was fixed before Fedora 19. The debugging I remember being asked to do at that time was: Get the firmware/lspci data for the devices.. and see if there were firmware updates (that fixed it for some other laptops back then). The other problem took some time as the kernel people had to figure out which cargo-cult god had to be appeased for it to work again. > While it's not a perfect solution, it makes my life happier.
