Hi, I've encountered the oops below running the r8712u driver. It occurred on Raspberry Pi (OpenELEC 5.95 beta, running kernel version 4.0.3), with the following device: > 0bda:8172 Realtek Semiconductor Corp. RTL8191SU 802.11n WLAN Adapter I'd be happy to dig in and see what the problem is, but I wanted to make sure this is the right driver to look at. linuxwireless.org says that this driver is going to be replaced by rtl8192su [1]. Have you seen this issue? Thanks, Haggai [1] http://linuxwireless.org/en/users/Drivers/rtl819x/ [ 834.537661] Unable to handle kernel paging request at virtual address a9d797d7 [ 834.544900] pgd = 96b14000 [ 834.547604]
