MacBook boot error
« on: May 28, 2012, 07:29:38 PM »
I am getting this error code during boot up on a MacBook 5,1 (late 2008)

Code: [Select]
pci_root PNP0A08:00: address space collision: host bridge window [mem 0x000cc000-0x000cffff] conflicts with Video ROM [mem 0x000c0000-0x000ce3ff]
The error is resolved with this workaround,  Boot code pci=nocrs   


I have searched online to find this error going way back to the 2.x kernel, and would have thought resource handling would have improved with the 3.0 kernel, maybe simply a BIOS bug??   or Kernel bug..??

Thoughts?  and is the boot code pci=nocrs a good idea??

The kernel people request everyone needing pci=nocrs to report a bug: https://bugzilla.kernel.org/

Though, please try the latest kernel first to see if it's still happening (3.4 as of this writing).
The only barriers that can stop you are the ones you create yourself.
