None of the below is relevant as of 2014-06-06, other than the possible need of reverting
sys/dev/pci/pci.c. I have confirmed that FreeBSD/i386 stable/8 r267147 works as expected on Dell OptiPlex GX260.
If you happen to run FreeBSD/i386 stable/8 on older Dell desktop PCs, like an OptiPlex GX260, you might want to back out r262226 prior to upgrading to the latest revision. The change done to
sys/dev/pci/pci.c in r262226 renders the kernel unable to mount the root filesystem.
Here’s what you should do (once) prior to running
make buildworld buildkernel on affected systems:
cd /usr/src svn up svn diff -r 262226:262225 sys/dev/pci/pci.c | patch
The above action will add the character
M to your kernel’s global revision number, indicating one or more local changes.
sys/dev/pci/pci.c be corrected for this deficiency in the future, you might want to revert the changes made above by running:
cd /usr/src svn revert sys/dev/pci/pci.c svn up
