Hi,
I noticed today that there is still a problem which has been there for at
least the last few kernel revisions. Using a pcmcia serial modem - either my
Zoom one or a brand new Creative Labs one, when the card is in the slot on
boot, trying to use it will come up with "modem is busy". Ejecting the card
will crash the kernel interupt handler. The modem CAN be used if it is
either inserted AFTER the computer is completely booted up, or if a
modprobe -r serial_cs followed by a modprobe serial_cs is done.
