etc/config.opts not considered

  • SuS

    Memory configured in etc/config.opts not allocated to Cardbus Modem

    I'm test-running Suse 10.1 on ASUS Laptop A4K with default SUSE kernel 2.6.16 and additionally tried several vanillakernels up to recent version 2.6.18-rc6-mm1.
    Using standard boot options my cardbus bridge is "hidden behind...." :
    <4>PCI: Bus #03 (-#06) is hidden behind  bridge #02 (-#03) (try 'pci=assign-busses')
    <4>Please report the result to linux-kernel to fix this permanently
    so I added "pci=assign-busses" to the kernel boot line (and then had to modify xorg.conf in order to keep X working).
    <3>PCI: Failed to allocate mem resource #10:2000000@0 for 0000:01:01.0
    <4>PCI: Bus 2, cardbus bridge: 0000:01:01.0
    <4>  IO window: 0000c000-0000c0ff
    <4>  IO window: 0000c400-0000c4ff
    <4>  PREFETCH window: 60000000-61ffffff
    <6>PCI: Bridge: 0000:00:0a.0
    <6>  IO window: c000-dfff
    <6>  MEM window: fba00000-feafffff
    <6>  PREFETCH window: 60000000-61ffffff
    <6>PCI: Bridge: 0000:00:0b.0
    <6>  IO window: 9000-bfff
    <6>  MEM window: fb900000-fb9fffff
    <6>  PREFETCH window: db800000-eb7fffff
    now, when inserting my Conceptronics Cardbus Modem into the slot it will be recognized, necessary modules are loaded:
    linux-S:/home/susanne # pccardctl info
    PRODID_1="Conceptronic MODEM"
    linux-S:/home/susanne # pccardctl ident
    Socket 0:
      product info: "Conceptronic MODEM", "56CLS", "5.41", ""
      manfid: 0x014e, 0x0088
      function: 2 (serial)
    linux-S:/home/susanne #

    - but any strange piece of software, think it's pcmcia_core modul, starts to probe always the same range of memory in order to make it available for the card - no matter what is defined in config.opts! - which results in :
    <6>Yenta: CardBus bridge found at 0000:01:01.0 [1043:1987]
    <6>hdc: ATAPI 24X DVD-ROM DVD-R CD-R/RW drive, 2048kB Cache, UDMA(33)

    <6>cs: IO port probe 0xc000-0xdfff: clean.
    <6>pcmcia: parent PCI bridge Memory window: 0xfba00000 - 0xfeafffff
    <6>pcmcia: parent PCI bridge Memory window: 0x60000000 - 0x61ffffff

    <5>pcmcia: registering new device pcmcia0.0
    <6>cs: IO port probe 0x100-0x3af: clean.

    and so prevents my card from working. The config.opts seems not to be checked anyway!
    Neither the sparely new pcmcia-howto on kernel.org nor further googling could lead me further...
    so I would appreciate any hint how to go on
    thanks and regards
    ps: I know provided info about my system is very incomplete but I hesitated to blow up that thread from the beginning...
