Hmm, ok, I would rather figure out why 2.6.31 is hanging, since 2.6.32 does not. Can you compile the latest 2.6.31 stable tree and use netconsole to capture the crash with CONFIG_USB_XHCI_HCD_DEBUGGING and CONFIG_USB_STORAGE_DEBUG turned on? (I assume you know how to use netconsole, but if you don't, I've posted how I setup netconsole at http://sarah.thesharps.us/2010-03-26-09-41) > I configured USB storage debugging and attached another log file.

I think the amount of information is fine, but I'm not sure why the device would respond with a stall to this particular command, so I'm CC'ing the USB storage list and SCSI list. Does anyone know what the third command is? The USB storage driver reports it as an "unknown command". I can see from scsi.h that 0x85 is the code for ATA_16, but I'm not sure what that command actually does.
