Hi Marek,
Can you boot following branch with "debug ignore_loglevel pci=realloc" on your setup?
git://git.kernel.org/pub/scm/linux/kernel/git/yinghai/linux-yinghai.git for-pci-allocate-fit-3.18
it has 8f74af9: PCI, x86: Allocate mmio near end of free range 1ff91c1: PCI: Don't allocate small resource in big free space. 108b43b: resources: Add allocate_resource_fit() b6a22f0: resources: Make find_resource could return just fit resource cf50e16: resources: Split out __allocate_resource()
on top the v3.18, and it will allocate resource in fit way.
Thanks
Yinghai
