Kernel config

[1.] When booting, I get a trace in rtl ending with a bad RIP value.

[2.] I have a boot failure (consistent) since about 3.17-rc7, which I have
bisected to

38506ecefab911785d5e1aa5889f6eeb462e0954 is the first bad commit
commit 38506ecefab911785d5e1aa5889f6eeb462e0954
Author: Larry Finger <Larry.Finger@lwfinger.net>
Date:   Mon Sep 22 09:39:19 2014 -0500

    rtlwifi: rtl_pci: Start modification for new drivers
    
    Future patches will move the drivers for RTL8192EE and RTL8821AE
    from staging to the regular wireless tree. Here, the necessary features
    are added to the PCI driver. Other files are touched due to changes
    in the various data structs.

This is extremely easy to test (boot) and seems 100% reproducible.

[3.] rtlwifi, rtl8192ce, rtl8188ce, v3.17

[4.]

[4.1.] This started happening near the end of 3.17's rcs.  A bisect
shows 38506ecefab911785d5e1aa5889f6eeb462e0954 as the first bad
commit.

[4.2] See attached for .config

[5.] I am currently running v3.17-rc6 without this issue.

[6.] N/A (I think)

[7.] N/A, though I can reproduce the issue by booting.
