It could be a combination of issues. ISTR that 2.6.32 does not have support for resetting configured USB devices. So if your PCIe software causes an error, and the SCSI layer tries to cancel a transfer and then reset the device, then I think that might be the cause of your issues. Can you try to update to 2.6.34?
