Also affects eventinj.
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. Jan
