I've got a Kingston Compact Flash adapter that I use to mount the flash
card of my digital camera.  I've had several problems with the kernel
with this, both 2.4.20, 2.5.69 and 2.5.72.

Both 2.4.20 and 2.5.69 works though, but oopses if I remove the card.
2.5.72 doesn't work at all:

(using yenta.ko)
Jun 18 21:09:19 [cardmgr] initializing socket 1
Jun 18 21:09:19 [cardmgr] socket 1: ATA/IDE Fixed Disk
Jun 18 21:09:19 [cardmgr] product info: "SanDisk", "SDP", "5/3 0.6"
Jun 18 21:09:19 [cardmgr] manfid: 0x0045, 0x0401  function: 4 (fixed disk)
Jun 18 21:09:19 [cardmgr] executing: 'modprobe ide-cs'
Jun 18 21:09:19 [cardmgr] bind 'ide-cs' to socket 1 failed: Invalid argument

I'm not sure what cardmgr tries to do with ide-cs, but it works with
2.5.69 but seems to have stopped working in 2.5.70 or 2.5.71 (didn't try
2.5.70) and is still not working in 2.5.72.  stracing cardmgr didn't help,
as the interesting parts are hidden inside a vfork which strace won't follow.

2.5.69 works (using yenta_socket.ko) and logs this:

Cardmgr is 3.2.4, pcmcia-cs is 3.2.4, gcc is 3.2.2.


I always seem to forget some vital information when reporting bugs, 
please don't hesitate to ask for more info.  I'll be happy to try any
patches to the kernel and/or cardmgr if needed.
