The IRQ init structs are marked as __initconst which means this memory can be free after init. On this platform, the PCI IRQ init happens very late _after_ the kernel already freed the memory allocated for these structs. During IRQ allocation, the allocation function is passed with invalid data at this point leading to following error: [ 0.000000] SoC: Qualcomm Atheros QCA9533 ver 2 rev 0 [ 2.382828] Freeing unused kernel memory: 264K [ 34.414816] pci 0000:00:00.0: no irq found for pin 1 and [ 0.000000] SoC: Qualcomm Atheros QCA956X ver 1 rev 0 [ 2.125401] Freeing unused kernel memory: 284K [ 9.526479] pci 0000:00:00.0: no irq found for pin 1 After this patch: [ 14.960814] pci 0000:00:00.0: using irq 40 for pin 1 Commit |
