Message-ID: <20120907001138.GB9279@gandalf.dynalias.org> Date: Fri, 7 Sep 2012 09:11:39 +0900 From: Norbert Preining <preining@...ic.at> To: linux-wireless@...r.kernel.org, linux-kernel@...r.kernel.org, Borislav Petkov <bp@...en8.de> Cc: Larry Finger <Larry.Finger@...inger.net> Subject: Re: rtl8192se hanging completely Hi all, (please cc) I have now changed my home router and with the new one it is working without problems at home, and with a few hickups at work, too. But still, at work after some time the connection breaks. I found the following interesting messages in the log: dmar: DRHD: handling fault status reg 3 dmar: DMAR:[DMA Read] Request device [03:00.0] fault addr fff73000 DMAR:[fault reason 06] PTE Read access is not set around the time the connection hangs and never comes back.

RTL8191SEvB Wireless LAN Controller (rev 10) Subsystem: Realtek Semiconductor Co., Ltd.

Any suggestions would be appreciated.
