Hi,
after installing more RAM in my IBM Thinkpad G40 laptop, I ran into the problem that PCMCIA ceased to work.
The problem turned out to have been reported to this list in 2003: http://www.ussg.iu.edu/hypermail/linux/kernel/0306.3/0956.html
For a 2.6 kernel the fix seems to be to either comment out pci_fixup_transparent_bridge in arch/i386/pci/fixup.c or to raise the value of pci_mem_start in arch/i386/kernel/setup.c.
However, none of these fixes have made it into mainline kernel (and I guess that is because they would break other platforms where the pci_fixup_transparent_bridge *is* needed). So lots of newer IBM Thinkpads with 1Gb RAM or more are unsupported with a vanilla kernel.
Now, the question is, is there any probability of a more specific fix being merged into the kernel and is there anyone with the code-fu to create such a patch?
Kind regards, David Härdeman
