Hi!
I see some problems in pcmcia subsystem in 2.6.12-rc4:
On compaq nx5000, inserting CF ide card is recognized as anonymous
memory. On compaq evo, it is recognized okay and
mounts/works. Unfortunately when I unplug the card, I get an oops:
Message from syslogd@Elf at Wed May 25 13:25:25 2005 ...
Elf kernel: Unable to handle kernel NULL pointer dereference at
virtual address 00000010
Message from syslogd@Elf at Wed May 25 13:25:25 2005 ...
Elf kernel: printing eip:

Elf kernel: Oops: 0000 [#1]
. -mm kernel actually works better on nx5000; it behaves similary to
-rc4 on evo; unfortunately it produces similar oops on card unplug.

This is full oops from -rc4 on compaq evo:

Yes, thanks, that works. Andrew, is there reason not to push that
patch into -mm/linus?

Full fix is in -mm (but still needs few changes).
