Subject: Fwd: PCMCIA not working on Panasonic Toughbook CF-29

Hi Dominik,
Please see attached the outputs that you asked for in 2 files. CF-29_MK5_2.6.32.txt is the requested outputs while running Antix Linux M8.5 with Kernel 2.6.32. CF-29_MK5_4.9.160.txt is the requested outputs running Antix Linux 17.4.1 with kernel 4.9.160.

Thank you in advance for your help!
Kind regards,Trevor Jacobs

Is this with 16-bit PCMCIA cards, or with 32-bit CardBus cards? Either case,
please provide the output of

    dmesg

    lspci -vvv

and

    lspcmcia -v -v

(ideally all for a working and non-working configuration).

Thanks,
    Dominik
