Is this indicative of a kernel or hardware problem?

[    0.279606] ACPI: Using IOAPIC for interrupt routing
[    0.279789] initcall acpi_init+0x0/0x216() returned with preemption imbalance
[    0.330789] ACPI: PCI Root Bridge [PCI0] (0000:00)

Thanks,
       Miles

That's a software bug.  Something under acpi_init() has mismatched
preempt_disable/preempt_enable or mismatched spin_lock/spin_unlock, etc.
