Hi again! :)

One more strange problem with BETA4 and usb-plugged HDD.

The hardware (the logs here are from BETA3, but i BETA4 the issue is still 
present, part of the logs is skipped to save the space):
intel centrino notebook, dmesg output follows

uhci0: <Intel 82801DB (ICH4) USB controller USB-A> port 0x1800-0x181f irq 10 
at device 29.0 on pci0
usb0: <Intel 82801DB (ICH4) USB controller USB-A> on uhci0
usb0: USB revision 1.0
uhci1: <Intel 82801DB (ICH4) USB controller USB-B> port 0x1820-0x183f irq 5 at 
device 29.1 on pci0 
usb1: <Intel 82801DB (ICH4) USB controller USB-B> on uhci1
usb1: USB revision 1.0
uhci2: <Intel 82801DB (ICH4) USB controller USB-C> port 0x1840-0x185f irq 10

uhci2: [GIANT-LOCKED]
usb2: <Intel 82801DB (ICH4) USB controller USB-C> on uhci2
usb2: USB revision 1.0
ehci0: <EHCI (generic) USB 2.0 controller> mem 0xd0000000-0xd00003ff irq 10 at 
device 29.7 on pci0
ehci0: [GIANT-LOCKED]
ehci_pci_attach: companion usb0
ehci_pci_attach: companion usb1
ehci_pci_attach: companion usb2
usb3: EHCI version 1.0
usb3: companion controllers, 2 ports each: usb0 usb1 usb2
usb3: <EHCI (generic) USB 2.0 controller> on ehci0
usb3: USB revision 2.0

Plugging in the USB2 hdd case after booting produces:
umass0: Genesys Logic USB TO IDE, rev 2.00/0.02, addr 2
da0 at umass-sim0 bus 0 target 0 lun 0
da0: <WDC WD16 00JB-00EVA0 0811> Fixed Direct Access SCSI-0 device 
da0: 1.000MB/s transfers
da0: 152627MB (312581808 512 byte sectors: 255H 63S/T 19457C)

I don't like this 1 MB/s transfer speed, and in reality it gives 8-9 MB/s.

Trying to boot with the case plugged in gives right after ata detection:
umass0: BBB reset failed, STALLED
umass0: BBB bulk-in clear stall failed, STALLED
umass0: BBB bulk-out clear stall failed, STALLED
