It's often difficult to pick a maintainer for a bug - it may not be the
fault of a single subsystem. As an example, I recently had a problem
getting USB and network to function (on kernels 2.5.5x). I noticed that
toggling Local APIC would also toggle which of the two devices worked.
Disabling ACPI allows both deviecs to function regardless of local APIC.

So, where is the problem?
1) Network driver? It doesn't work with ACPI and both Local APIC and
2) USB driver? It doesn't work with ACPI and no UP APIC.
3) APIC? Causes weird problems with various drivers when ACPI is turned on.
4) ACPI? Causes weird problems with various drivers when APIC is toggled.

(this exact bug was in Bugzilla, though I hadn't checked there before
mailing lkml ;)

I'm not exactly a neophyte to the kernel, and I would have to do a lot
more digging to find the right maintainer to send this to. Also, the
person(s) to whom the bug is reported will depend on how much debugging
work I do, and in what order I do it.

I'm not trying to discourage you - just raising a potential gotcha.
