    Hi

    After I got a new Toshiba r100 laptop (from a Dell latitude) my 3com bluetooth pcmcia card startet killing my laptop. It uses the serial_cs driver and worked well before, but now when I add the card, the system freezes and I have to reboot.

    System infos:
    Gentoo Linux
    Kernel 2.6.7 (own kernel)
    pcmcia-cs version 3.2.7
    Toshiba R100 Laptop (yento_socket)

      Do you have any other PCMCIA cards, or is this the only one you can try?

      It could be a few things.  Maybe the IO port range and/or interrupt being assigned to the card conflicts with some other device.  Or maybe the memory probe that happens when a card is first inserted is causing the problem.

      Hi

      I'm really sorry about the delay.

      This is what I've found out so far. When I plug in the card or start pcmcia with the card in the slot, my computer hangs. If I remove it fast enough, the computer comes back to life.
      This is the dmegs output:
      Yenta: CardBus bridge found at 0000:02:0b.0 [1179:0001]

      and the /var/log/messages:

      I just upgraded to kernel 2.6.9.

        Well, the first thing I'd try would be to add:

          exclude port 0x100-0x10f

        to /etc/pcmcia/config.opts on the theory that it might be an IO port conflict.

        I'm assuming that re-inserting the card after you've rescued it also results in a lockup?

      Thanks for the reply

      First I have tried a few other cards (network, externel cdrom drive) and they both work just fine.

      Second, I tried 'exclude port 0x100-0x10f' in config.opts, but it didn't help.

      No, if i reinsert the card afterwards it still freezes.
      Could it be a conflict on irq 11?

        I don't think it can be an interrupt conflict, if your other cards work ok.  I think the problem is that the kernel serial_cs driver is misdetecting the card as a dual port device.

        Can you temporarily comment out the device definition for the serial_cs driver in /etc/pcmcia/config (so that your system doesn't lock up), and then post the output of 'dump_cis' with this card inserted?

          Okay. I commented out device "serial_cs" ... in /etc/pcmcia/config

          Here is my dump_cis:

          Socket 0:
            dev_info
              NULL 0ns, 512b
            manfid 0x0101, 0x0041
            funcid serial_port [post]
            serial_interface
              uart 16550 [space/mark/odd/even] [5/6/7/8] [1/1.5/2]
            vers_1 7.1, "3Com", "3CRWB6096B Bluetooth PC Card", "", ""
            config base 0x00f8 mask 0x000f last_index 0x02
            cftable_entry 0x01 [default]
              [rdybsy]
              Vcc Vnom 3300mV Iavg 70mA
              io 0x0000-0x000f [lines=4] [8bit] [range]
              irq mask 0xffff [level] [shared]
            cftable_entry 0x02 [default]
              [rdybsy]
              Vcc Vnom 5V Iavg 70mA
              io 0x0000-0x000f [lines=4] [8bit] [range]
              irq mask 0xffff [level] [shared]

          I did notice in my kernel config some options under
          Character Devices ->
                  Serial Drivers ->
                        PCMCIA device support
          Some stuff like 'Support for sharing serial intetrupts'  and more.

          Is that related?

          Thanks,

          Nic
