I wonder if some can help me sorting out the problems that I am experiencing
with the above hardware (even with pointers to helpful discussions on this ml).
1) the kernel can see the insertion of a pcmcia card
2) the pcmcardctl ident command correctly identifies the card
3) the serial_cs module gets correctly loaded
4) udev makes /dev/ttyS0 point to a new device in the sys hierarchy
5) the card starts flashing its led in the way it is expected to do
but
6) lspci cannot see the card
It shouldn't, for it isn't a PCI card.
Right!!!
7) dmesg stops at the pcmcia 0.0: registering new device (printed twice, both
for pcmcia 0.0 and 0.1), but does not say anything like 0.0: ttyS0 at I/0 0x3F8
(irq = 19) is a 16550A as other laptops do with the same card.
8) ttyS0 remains not responsive.
Could you post the output of "lspcmcia -vvv" (executed as root), please? I
suspect that this laptop does need more resources available (using a
resource database etc.)...
Sure. Sorry for the delay, but I had to put my hands physically on that
laptop in order to be able to make the check

For comparison purposes, I can also give you the same output on a DELL
laptop where the novatel card does actually work

What is definitively different is the available IRQs.
Best regards,
