Thank you for the suggestion, but that flag was added in 2016 to the aacraid driver. > commit 0910d8bbdd99856af1394d3d8830955abdefee4a > Author: Hannes Reinecke <hare@xxxxxxx> > Date: Tue Nov 8 08:11:30 2016 +0100 > > scsi: aacraid: switch to pci_alloc_irq_vectors > > Use pci_alloc_irq_vectors and drop the hand-crafted interrupt affinity > routines. So what would happen, if `PCI_IRQ_AFFINITY` was removed? Will the system still work with the same performance? As far as I understood, the no regression policy is there for exactly that reason, and it shouldn’t matter if it’s core infrastructure or not. As written, I have no idea, and just know reverting the commit in question fixes the problem here. So I’ll gladly test other solutions to fix this issue. Kind regards, Paul
