Cuando la configuraci\u00f3n de VSI fall\u00f3 en i40e_probe() como parte de la configuraci\u00f3n del conmutador PF, el controlador intentaba liberar vectores IRQ miscel\u00e1neos en i40e_clear_interrupt_scheme y produjo un kernel Oops: Intentando liberar IRQ 266 que ya est\u00e1 libre ADVERTENCIA: CPU: 0 PID: 5 en kernel/irq/manage.c:1731 __free_irq+0x9a/0x300 Cola de trabajo: eventos work_for_cpu_fn RIP: 0010:__free_irq+0x9a/0x300 Seguimiento de llamadas: ? synchronize_irq+0x3a/0xa0 free_irq+0x2e/0x60 i40e_clear_interrupt_scheme+0x53/0x190 [i40e] i40e_probe.part.108+0x134b/0x1a40 [i40e] ? kmem_cache_alloc+0x158/0x1c0? acpi_ut_update_ref_count.part.1+0x8e/0x345? acpi_ut_update_object_reference+0x15e/0x1e2? chain+0x21/0x70 ? irq_get_irq_data+0xa/0x20 ? mp_check_pin_attr+0x13/0xc0? irq_get_irq_data+0xa/0x20 ? mp_map_pin_to_irq+0xd3/0x2f0? acpi_register_gsi_ioapic+0x93/0x170? pci_conf1_read+0xa4/0x100? pci_bus_read_config_word+0x49/0x70? do_pci_enable_device+0xcc/0x100 local_pci_probe+0x41/0x90 work_for_cpu_fn+0x16/0x20 Process_one_work+0x1a7/0x360 worker_thread+0x1cf/0x390 ? create_worker+0x1a0/0x1a0 kthread+0x112/0x130? kthread_flush_work_fn+0x10/0x10 ret_from_fork+0x1f/0x40 El problema es que en ese momento a\u00fan no se hab\u00edan asignado varios vectores IRQ y obtenemos un seguimiento de llamada de que el controlador est\u00e1 intentando liberar vectores IRQ que ya est\u00e1n libres. Agregue una verificaci\u00f3n en i40e_clear_interrupt_scheme para el estado __I40E_MISC_IRQ_REQUESTED PF antes de llamar a i40e_free_misc_vector. Este estado se establece solo si se inicializaron correctamente varios vectores IRQ.\"}],\"metrics\":{},\"references\":[{\"url\":\"https://git.kernel.org/stable/c/17063cac4088b8e2fc0f633abddca5426ed58312\",\"source\":\"416baaa9-dc9f-4396-8d5f-8c081fb06d67\"},{\"url\":\"https://git.kernel.org/stable/c/2e5a20573a926302b233b0c2e1077f5debc7ab2e\",\"source\":\"416baaa9-dc9f-4396-8d5f-8c081fb06d67\"},{\"url\":\"https://git.kernel.org/stable/c/60ad4cde0ad28921f9ea25b0201c774b95ffa4b4\",\"source\":\"416baaa9-dc9f-4396-8d5f-8c081fb06d67\"},{\"url\":\"https://git.kernel.org/stable/c/75099439209d3cda439a1d9b00d19a50f0066fef\",\"source\":\"416baaa9-dc9f-4396-8d5f-8c081fb06d67\"},{\"url\":\"https://git.kernel.org/stable/c/97aeed72af4f83ae51534f0a2473ff52f8d66236\",\"source\":\"416baaa9-dc9f-4396-8d5f-8c081fb06d67\"},{\"url\":\"https://git.kernel.org/stable/c/17063cac4088b8e2fc0f633abddca5426ed58312\",\"source\":\"af854a3a-2127-422b-91ae-364da2661108\"},{\"url\":\"https://git.kernel.org/stable/c/2e5a20573a926302b233b0c2e1077f5debc7ab2e\",\"source\":\"af854a3a-2127-422b-91ae-364da2661108\"},{\"url\":\"https://git.kernel.org/stable/c/60ad4cde0ad28921f9ea25b0201c774b95ffa4b4\",\"source\":\"af854a3a-2127-422b-91ae-364da2661108\"},{\"url\":\"https://git.kernel.org/stable/c/75099439209d3cda439a1d9b00d19a50f0066fef\",\"source\":\"af854a3a-2127-422b-91ae-364da2661108\"},{\"url\":\"https://git.kernel.org/stable/c/97aeed72af4f83ae51534f0a2473ff52f8d66236\",\"source\":\"af854a3a-2127-422b-91ae-364da2661108\"}]}}"
