Jan, Problem is that your system doesn't have proper SMP tables and we
were doing enable_IR_x2apic() twice finally leading to this panic. Can
you please check if the appended patch fixes your issue? Thanks.

From: Suresh Siddha <suresh.b.siddha@xxxxxxxxx>
Subject: x86: fix calling enable_IR_x2apic() twice with SMP kernel on !SMP boards
Jan Grossmann reported kernel boot panic while booting SMP kernel on his
system with a single core cpu. SMP kernels call enable_IR_x2apic() from
native_smp_prepare_cpus() and on platforms where the kernel doesn't
find SMP configuration we ended up again calling enable_IR_x2apic() from the
APIC_init_uniprocessor() call in the smp_sanity_check(). Thus leading to
kernel panic.
Don't call enable_IR_x2apic() and default_setup_apic_routing()
from APIC_init_uniprocessor() in CONFIG_SMP case.

The patch seems to work,
but now my kernel won't find any IDE, SATA or USB drives anymore and
then i end up with
Kernel panic - not syncing: VFS: Unable to mount root fs on
unknown-block(0,0)
of course.
the full boot log is attached.
thanks
