| This information relates to error messages such as the one outlined in the page title and other similar ones - for example:
| |
|
| |
| <pre>
| |
| pci_root PNP0A08:00: address space collision: host bridge window [mem
| |
| 0x000cc000-0x000cffff] conflicts with Video ROM [mem 0x000c0000-0x000ce9ff]
| |
| </pre>
| |
|
| |
| 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 - [https://bugzilla.kernel.org/show_bug.cgi?id=16497 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 [https://bugzilla.kernel.org 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
| |
|
| |
| Example:
| |
|
| |
| <pre>
| |
| timeout 20
| |
| prompt 1
| |
| default grsec
| |
| label grsec
| |
| kernel /boot/grsec
| |
| append pci=nocrs initrd=/boot/grsec.gz alpine_dev=usbdisk:vfat modules=loop,cramfs,sd-mod,usb-storage quiet
| |
| </pre>
