Here is what I see now: isci0: <Intel(R) C600 Series Chipset SAS Controller (SATA mode)> port 0x6000-0x60ff mem 0xde07c000-0xde07ffff,0xddc00000-0xddffffff irq 16 at device 0.0 on pci10 isci0: attempting to allocate 2 MSI-X vectors (2 supported) ISCI: isci->num_interrupts: 2 max_msix_messages: 2 isci: 1:000089 ISCI bus_alloc_resource failed The storm is still there. Will now set hw.isci.force_legacy_interrupts=1 and check if the device then works correctly. Lars
