Is this a multi-slot card reader style device? It seems the memstick r592 and MTD r852 drivers are somehow racing on a card insertion. What happens if you blacklist one or the other? It is an integrated card reader that can read multiple types of cards. When I do "modprobe -r r592" (and ensure by lsmod it is no longer loaded), then push the card in and out, I get the following messages: Oct 5 12:57:35 kparal kernel: [ 136.168294] r592 0000:15:00.4: PCI INT C disabled Oct 5 12:57:50 kparal kernel: [ 150.747143] r852: detected xD writeable card in slot Oct 5 12:57:50 kparal kernel: [ 151.048213] NAND device: Manufacturer ID: 0x98, Chip ID: 0x71 (Toshiba xD 256MiB 3,3V) Oct 5 12:57:50 kparal kernel: [ 151.098408] NMI: PCI system error (SERR) for reason b1 on CPU 0.
