Hi all,

the commit "PCI: update bridge resources to get more big ranges when allocating space (again)"

http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commitdiff;h=da7822e5ad71ec9b745b412639f1e5e0ba795a20

kills my SD-Card and the PCMCIA slot on a Dell E6510 with the latest 3.0.0-rc2 ...

When i revert the commit both the MMC/SD stuff and the PCMCIA re-appears.

Any idea?

See my attached boot.diff / kernel config 

Regards,
Oliver
