    Subjectserial CardBus card does not wake up after sleep
    Hi,

    I'm using a serial CardBus card (Sony Ericsson GC79 -- combined GPRS and
    WiFi, I'm talking about the GPRS modem part of it) in a Samsung P35
    laptop, kernel version 2.6.11. If I put the laptop in S3 leaving the
    card in the laptop, the card does not wake up on resume. I need to
    remove and reinsert the card.

    If I suspend the laptop having an open ppp-session, the session is dead
    after resume. It takes long for pppd to exit (ctrl-c), and when I remove
    the card, I get the "kernel BUG" message pasted below.

    This is what lspci tells me about the card:
    ----------8<--------------
    07:00.0 Network controller: Broadcom Corporation: Unknown device 4320 (rev 03)
    Subsystem: Unknown device 18de:0002

    Flags: fast devsel, IRQ 11
    I/O ports at 4c00 [size=256]
    ----------8<--------------


    That's what I find in the logfiles:
