Did you get any response as to whether it was going to be accepted into
the kernel or not?

The unfortunate thing is that even this sort of fix will not help my
situation. The reason being (which I only discovered by accident when I
set "dont_enable_local_apic = 1" rather than "dont_use_local_apic_timer"
and it didn't correct the booting problem) is that it seems that even if
the local apic is set disabled by setting dont_enable_local_apic = 1 in
arch/i386/kernel/apic.c, setup_APIC_clocks() is still called.

So the jist is that using the local apic timer feature is not dependent on
using the local apic, as per the dont_enable_local_apic and
dont_use_local_apic_timer flags in arch/i386/kernel/apic.c. Maybe this is
wrong, I dunno unfortunately.

I don't know anything about this APIC stuff so I don't know if that is
correct or not, but it is what happens.

Thanx for the input though, much appreciated,

b.
