When you have a moment, consider changes from the following series: https://git.kernel.org/pub/scm/linux/kernel/git/pci/pci.git/log/?h=sysfs Test, and let us know if this fixes the problem for you. I would appreciate if you could test this for us. > Do you know what could be causing the duplicate file here? The series cover letter has a bit of information about what is going on here, and why, see: https://lore.kernel.org/linux-pci/20260508043543.217179-1-kwilczynski@kernel.org/#t Hope this helps. Thank you! Krzysztof
