Error message on boot: Address space collision: host bridge window conflicts with Adaptor ROM
Adaptor ROM Conflicts

This page was created in early 2011; is it still relevant? If not, let's delete.
This information relates to error messages such as the one outlined in the page title and other similar ones - for example:
pci_root PNP0A08:00: address space collision: host bridge window [mem 0x000cc000-0x000cffff] conflicts with Video ROM [mem 0x000c0000-0x000ce9ff]
This error message occurs due to the way 2.6.34 and later kernels enumerate PCI host bridges and is not specific to Alpine Linux - see this kernel bug report. The message itself does not indicate a functional problem, so it can be ignored.
If you see additional problems, such as computers with multiple NICs not starting all adaptors reliably and issues with multi display/adaptor configurations, please report them in the kernel bugzilla and attach a complete dmesg log. The "pci=nocrs" parameter may be a workaround while debugging the problem.
To use "pci=nocrs", edit the syslinux.cfg boot file and add pci=nocrs to the parameters. On systems that boot from a USB memory stick, this file is /media/usb/syslinux.cfg
