Unfortunatly it panics on my AMD Kaveri system with IOMMU enabled in drivers/pci/msi.c: static void msi_set_mask_bit(struct irq_data *data, u32 flag) { struct msi_desc *desc = irq_data_get_msi(data); if (desc->msi_attrib.is_msix) { <-- at this line something goes wrong msix_mask_irq(desc, flag); readl(desc->mask_base); /* Flush write to device */ } else { unsigned offset = data->irq - desc->irq; msi_mask_irq(desc, 1 << offset, flag << offset); } } I am further investigating to find out what went wrong, but maybe you also have an idea?
