quirks on my motherboard/BIOS or possibly Unicorn hardware and not caused
by the Unicorn driver.
It only arises when the BIOS allocates Unicorn a shared IRQ with
the motherboard VT8233 AC97 audio chip. The kernel ACPI code
Hmmm, seems like there is an IRQ sharing problem. I reconfigured the
hardware recently and I am now getting the following backtrace:
[ 105.764004] irq 10: nobody cared (try booting with the irqpoll option)

code, pci_dev-irq claims that it is using IRQ 10. However the kernel
ACPI code claims that it is
