I found this fix from for-linus branch: # PCI: Fix missing lockdep annotation for pci_cfg_access_trylock()for-linus https://git.kernel.org/pub/scm/linux/kernel/git/pci/pci.git/commit/?h=for-linus&id=f941b9182c54a885a9d5d4cfd97af66873c98560 But at least that doesn't fix my crash. -- https://patchwork.kernel.org/project/linux-wireless/list/ https://wireless.wiki.kernel.org/en/developers/documentation/submittingpatches
