My Ubuntu hangs at boot with message "Attached scsi removable disk". When I boot with param acpi=off, system boots fine. I'm booting from harddrive, not from usb device. I managed to locate source of this problem to the external card reader & usb hub, into which I have connected external keyboard and mouse. If i disconnect it (whole card reader & usb hub), system boots fine.

Could you suggest any way to boot successfully without adding acpi=off or disconnecting hub&reader before booting?

Output of dmesg after successful boot with acpi=off:
