It was suppose to be fixed by this patch: https://patchwork.kernel.org/project/linux-scsi/patch/154422179851.1218.10349207247849277036.stgit@brunhilda/ I can see that Hellwig added back PCI_IRQ_AFFINITY flag in commit 5219822687be ("scsi: smartpqi: switch to pci_alloc_irq_vectors"). Is there another way I can control which CPU that process IRQs from the disk controller? --Jesper (lspci output below) b2:00.0 Serial Attached SCSI controller: Adaptec Smart Storage PQI SAS (rev 01) Kernel driver in use: smartpqi Kernel modules: smartpqi Don: Can you tell us what OS you are running and the driver version?
