Did you really meet the case and this patch solves it? By the changes of d0311314d002, I can't really understand why the initial version and the commit do. Considering the commit "fix" some situations, I don't know if this patch would break them again. Could you look into rtlwifi PCI flow deeper and share your ideas?
