Hi,
I get the following error when cold booting, it doesn't seem to happen
after a restart:

I have just moved my installation to a new machine with a:
03:00.0 Network controller: Realtek Semiconductor Co., Ltd. RTL8188CE
802.11b/g/n WiFi Adapter (rev 01)
Subsystem: Realtek Semiconductor Co., Ltd. Device 8195
Kernel driver in use: rtl8192ce
Kernel modules: rtl8192ce
Linux jamie-laptop 3.0-ARCH #1 SMP PREEMPT Tue Aug 30 08:53:25 CEST
2011 x86_64 Intel(R) Core(TM) i5-2410M CPU @ 2.30GHz GenuineIntel
GNU/Linux
I am reporting it here as I assume it's a rtl8192ce bug, but if not I
can report it to the wpa_supplicant guys.
Thanks, Jamie

The bug is not necessarily caused by rtl8192ce. I have never seen this problem
on my system. I would also expect a stack dump. Anyone know what is needed to
get one here?
I do have some further questions.
Which variant of the RTL8188CE do you have? Use 'lspci -nn' to tell.
Does ARCH have an updated kernel later than 3.0?
What version of wpa-supplicant?
Are you using NetworkManager? If so, what version? Is your desktop KDE, Gnome,
or something else? If NM, what applet and version?
If not NM, how do you connect?

03:00.0 Network controller [0280]: Realtek Semiconductor Co., Ltd.
RTL8188CE 802.11b/g/n WiFi Adapter [10ec:8176] (rev 01)

Looks like I am using the latest core of 3.0.4, there's 3.0.6 in testing:
http://www.archlinux.org/packages/testing/x86_64/linux/
Might that help?

wpa_supplicant v0.7.3

I use dwm and wpa_supplicant, no manager.
Thanks, Jamie

Probably not. I think all the changes in the mainline 3.1-rc8 are in 3.0.4.

That is what I use.

I know nothing of dwm, but the driver works on my system with both NM and with ifup.
