Remove pcmcia card, system hangs

[hseaver@nospamcybershamanix.com]

When I remove the card, the whole
system hangs. Totally -- can't log in from the network, if top is running it
stops, etc. Have to do a hard reboot. I've tried installing the latest
pcmcia-cs. Otherwise pcmcia works fine, it correctly ID's the flash card I put
in, reads it, writes to it.
Here's what it says in /var/log/messages when I insert the card:

Sep 3 21:01:40 cybershamanix cardmgr[1516]: socket 0: ATA/IDE Fixed Disk
Sep 3 21:01:40 cybershamanix kernel: cs: memory probe 0x0d0000-0x0dffff:
clean.
Sep 3 21:01:40 cybershamanix cardmgr[1516]: executing: 'modprobe ide-cs'

Sep 3 21:01:43 cybershamanix cardmgr[1516]: executing: './ide start hdc'

So I can can then mount /dev/hdc1 on /mnt/temp, read it, write to it, then
unmount it, pull out the card and bam! the machine locks up.

One thing else I've noticed is that if I do an "fdisk /dev/hdc" either
before or after I put in the flash card, I get the partition table for what is
actually /dev/hda. If I do a fdisk /dev/hdc1, then I get the correct partion
table, but that's weird.

For some reason my laptop has been doing the same thing. Here is a simple
work around to the problem, for now.

1) insert pcmcia card and do what ever you are going to do

2) before removeing the card issue the following command

cardctl eject (that will eject all of the card slots)

3) now physicaly remove the card, no lock ups ;-)
