I have two different revisions of the RTL8188CE card. The newer one, marked
RTL8188CE-VL, gives the following lspci output:

It certainly does not yield the rx descriptor problem. Please send the lspci
output when the driver has not been loaded.
The subsystem ID is different on my wireless card (8212):
06:00.0 Network controller [0280]: Realtek Semiconductor Co., Ltd. RTL8188CE 802.11b/g/n WiFi Adapter [10ec:8176] (rev 01)

This id is nowhere to be found in the rtlwifi driver. The only matches in
Google are my previous problem report (FWLPS freeze) and windows driver
listings.
The ID that counts is the first one. I think the second is some kind of vendor code.
My other RTL8188CE gives the following output:

Other than the MAC address, and the bus number, they have the same output.
Note, the RTL8188CE-VL does not work with wireless-next, but does with
wireless-testing with some patches applied. I will contact the Realtek software
team to ask questions about your card. I added my contact as a Cc here. In the
meantime, could you try the wireless-testing tree? If your card still does not
work, I will send you some patches to see what it takes.
