That exposed a situation where IRQs weren't freed if a PCI error recovery system opts to remove the device. For such case the pci channel state is set to pci_channel_io_perm_failure and ixgbe_io_error_detected was returning PCI_ERS_RESULT_DISCONNECT before calling ixgbe_close_suspend consequentially not freeing IRQ and crashing when the remove handler calls pci_disable_device, hitting a BUG_ON at free_msi_irqs, which asserts that there is no non-free IRQ associated with the device to be removed: BUG_ON(irq_has_action(entry->irq + i)); The issue is fixed by calling the ixgbe_close_suspend before evaluate the pci channel state.
