Public bug reported:
Currently the Ubuntu kernels ship with CONFIG_EISA_VLB_PRIMING=y. This
doesn't match the upstream default (n) and this is the help text:
Activate this option if your system contains a Vesa Local
Bus (VLB) card that identify itself as an EISA card (such as
the Adaptec AHA-284x).
When in doubt, say N.
I noticed this actually changes the kernel behavior such that it forces
the probing code to probe EISA slots even when it cannot find an EISA
compliant mainboard.
This manifests in a collection of warnings on every boot.

[ 0.989961] platform eisa.0: Cannot allocate resource for EISA slot 7
[ 0.990646] platform eisa.0: Cannot allocate resource for EISA slot 8
I think this config option should be changed to match upstream default
for Ubuntu kernels.
