Re: rtl8192se hanging completely

[Norbert Preining]

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.

The mentioned device 03:00.0 is the wlan adapter:
$ lspci -v -s 03:00.0
03:00.0 Network controller: Realtek Semiconductor Co., Ltd. RTL8191SEvB Wireless LAN Controller (rev 10)
	Subsystem: Realtek Semiconductor Co., Ltd. Device e020
	Flags: bus master, fast devsel, latency 0, IRQ 17
	I/O ports at 2000 [size=256]
	Memory at f0500000 (32-bit, non-prefetchable) [size=16K]
	Capabilities: [40] Power Management version 3
	Capabilities: [50] MSI: Enable- Count=1/1 Maskable- 64bit+
	Capabilities: [70] Express Legacy Endpoint, MSI 00

	Capabilities: [160] Device Serial Number 88-55-22-fe-ff-4c-e0-00
	Kernel driver in use: rtl8192se
$

That is with latest git kernel from yesterday.

Any suggestions would be appreciated.
