If it's not the scsi_bus_uevent problem, then no, it isn't. The odd thing is that it occurs in the middle of USB initialisation fro= m the log: > =EF=BB=BFJun 6 17:25:19 upstairs kernel: uhci_hcd 0000:00:1d.0: UHCI= Host Controller=20 > Jun 6 17:25:19 upstairs kernel: uhci_hcd 0000:00:1d.0: new USB bus r= egistered, assigned bus number 1=20 > Jun 6 17:25:19 upstairs kernel: uhci_hcd 0000:00:1d.0: irq 16, io ba= se 0x0000a800=20 > Jun 6 17:25:19 upstairs kernel: usb usb1: configuration #1 chosen fr= om 1 choice=20 > Jun 6 17:25:19 upstairs kernel: hub 1-0:1.0: USB hub found=20 > Jun 6 17:25:19 upstairs kernel: hub 1-0:1.0: 2 ports detected=20 > Jun 6 17:25:44 upstairs kernel: ohci_hcd: 2006 August 04 USB 1.1 'Op= en' Host Controller (OHCI) Driver=20 > Jun 6 17:25:44 upstairs kernel: usb usb1: New USB device found, idVe= ndor=3D1d6b, idProduct=3D0001=20 > Jun 6 17:25:44 upstairs kernel: usb usb1: New USB device strings: Mf= r=3D3, Product=3D2, SerialNumber=3D1=20 > Jun 6 17:25:44 upstairs kernel: usb usb1: Product: UHCI Host Control= ler=20 > Jun 6 17:25:44 upstairs kernel: usb usb1: Manufacturer: Linux 2.6.26= -rc5 uhci_hcd=20 Note the jump from 19 to 44 seconds.

Perhaps turning on driver core debuggin= g might help (that's CONFIG_DEBUG DRIVER ... it depends on CONFIG_DEBUG_KERNEL for activation). Hopefully the verbose kernel logs from here might tell us what's going on in the lacunae.
