Well I was assuming you'd code this up in the driver not arbitarily - and you need to do that for IRQ anyway. So something like
writel(0xFFFFFFFF, &mdev->irq_mask); pci_mark_failed(pdev, PCI_TRY_REPLUG|PCI_TRY_D3); spin_unlock(&mylock); return -EXPLODED;
with pci_mark_failed firing off any replug via a work queue
