I finally got around to testing this, and while I still have problems with that reader, I can't reproduce the oops with that patch in place either. Of course, I only ever saw the oops once, so I really don't know how reproducible it was. Maybe you have to remove the USB reader at _just_ the right moment. But I did get ... usb 2-6: reset high speed USB device using ehci_hcd and address 4 usb 2-6: USB disconnect, address 4 sd 6:0:0:1: [sdc] Result: hostbyte=0x07 driverbyte=0x00 end_request: I/O error, dev sdc, sector 1999855 ... scsi 6:0:0:1: rejecting I/O to dead device so the testing was done with the kind of behaviour that resulted in an oops and a dead khubd last time around. So I guess I'll ack the patch for whatever that is worth. Over to you, Greg..
