kernel page fault in r8712u

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



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
