I tried booting kernel 3.0.2 (debian/unstable 3.2.0-rc4-amd64) with a USB key plugged into USB 3.0 and was stuck again. So I can confirm that with a normal USB key (non-HID) plugged in USB 3.0 port, makes the kernel refuse to boot. After a normal boot, key appears as : [ 158.736727] usb 3-2: new high-speed USB device number 2 using xhci_hcd [ 158.755680] xhci_hcd 0000:03:00.0: WARN: short transfer on control ep [ 158.756522] xhci_hcd 0000:03:00.0: WARN: short transfer on control ep [ 158.757426] xhci_hcd 0000:03:00.0: WARN: short transfer on control ep [ 158.758299] xhci_hcd 0000:03:00.0: WARN: short transfer on control ep [ 158.758698] usb 3-2: New USB device found, idVendor=0951, idProduct=160f [ 158.758708] usb 3-2: New USB device strings: Mfr=1, Product=2, SerialNumber=3 [ 158.758714] usb 3-2: Product: DT Mini Slim [ 158.758719] usb 3-2: Manufacturer: Kingston [ 158.758723] usb 3-2: SerialNumber: 0019E06B07B5F9A1879A0D15 [ 158.760294] scsi7 : usb-storage 3-2:1.0 [ 159.760670] scsi 7:0:0:0: Direct-Access Kingston DT Mini Slim 1.00 PQ: 0 ANSI: 2 [ 159.763089] sd 7:0:0:0: Attached scsi generic sg2 type 0 [ 159.763655] sd 7:0:0:0: [sdb] 15654848 512-byte logical blocks: (8.01 GB/7.46 GiB) [ 159.763834] sd 7:0:0:0: [sdb] Write Protect is off [ 159.763841] sd 7:0:0:0: [sdb] Mode Sense: 16 0f 09 51 [ 159.764012] sd 7:0:0:0: [sdb] Incomplete mode parameter data [ 159.764019] sd 7:0:0:0: [sdb] Assuming drive cache: write through [ 159.765193] sd 7:0:0:0: [sdb] Incomplete mode parameter data [ 159.765200] sd 7:0:0:0: [sdb] Assuming drive cache: write through [ 159.765778] sdb: sdb1 [ 159.766855] sd 7:0:0:0: [sdb] Incomplete mode parameter data [ 159.766865] sd 7:0:0:0: [sdb] Assuming drive cache: write through [ 159.766875] sd 7:0:0:0: [sdb] Attached SCSI removable disk >> As suggested by Jonathan N.

Is there a way to check if bug is related to ACPI or rather USB 3.0 ?
