2.4.17-pre2 & PCMCIA Errors

[Alan Ford]

Just tried 2.4.17-pre2 (was previously on 2.4.16-pre1) and when pcmcia-cs is
started on bootup, the following happens:

cs: IO port probe 0x0c00-0x0cff: clean.
cs: IO port probe 0x0100-0x04ff: excluding 0x4d0-0x4d7
cs: IO port probe 0x0a00-0x0aff: clean.
cs: memory probe 0xa0000000-0xa0ffffff:<1>Unable to handle kernel NULL pointer
dereference at virtual address 00000004
 printing eip:

If I run cardctl, I'll get the same error ("Unable to handle kernel NULL
pointer dereference at virtual address 00000004")

Can anybody enlighten me? Is this a kernel bug or have I got something
misconfigured that just happened to work before (if so, can that "feature"
be put back please? :) )

Am using Debian with pcmcia-cs 3.1.29-3. Laptop is a Dell Insprion 8K 
(CardBus controller is a TI PCI4451).
