This issue is caused by a bug in the user space irqchip chain:
pic_update_irq triggered by the test case's mask_pic_interrupts fails to
reset the CPU IRQ on x86.
I've applied the testdev patch to an ancient i8259&Co. cleanup queue of
mine, and that actually fixes the issue. I guess I should rebase those
patches and post them eventually.
