Hi Greg, we've got a regression report on the recent 4.4.x kernel; namely, Realtek WiFi gives an Oops. The details are found at: https://bugzilla.suse.com/show_bug.cgi?id=1026462 The regression was introduced in 4.4.41 by the backport of ba9f93f82aba ("rtlwifi: Fix enter/exit power_save"), which prerequisites the fix 60f59ce0278557 ("rtlwifi: rtl_usb: Fix missing entry in USB driver's private data"). It was confirmed that backporting the latter commit fixes the issue. Could you cherry-pick 60f59ce0278557 to 4.4.x stable tree? thanks, Takashi
