I meant kernel packages and not boot images, sorry. You answered my question, thanks so much.
After setting iommu=soft, I noticed that the kern.log file was getting quite huge. I noticed there are a large number (over 31 millions) of errors like this: Dec 13 08:25:01 HP kernel: [25953.936777] hub 10-1:1.0: hub_port_status failed (err = -22) Dec 13 08:25:01 HP kernel: [25953.936781] hub 10-1:1.0: hub_port_status failed (err = -22) Dec 13 08:25:01 HP kernel: [25953.936785] hub 10-1:1.0: hub_port_status failed (err = -22) Dec 13 08:25:01 HP kernel: [25953.936788] hub 10-1:1.0: hub_port_status failed (err = -22) Dec 13 08:25:01 HP kernel: [25953.936791] hub 10-1:1.0: activate --> -22 I verified the status of the USB hub and all ports have a status of "active". The ep_81 status says disable. I think I'll have to dig more into this and understand what's the significance of those entries in kern.log.
