(Sending this to the right people this time, hopefully.)
I have been getting a consistent boot failure with 3.17, which I have
bisected to
38506ecefab911785d5e1aa5889f6eeb462e0954 is the first bad commit
commit 38506ecefab911785d5e1aa5889f6eeb462e0954
Author: Larry Finger <Larry.Finger@xxxxxxxxxxxx>

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.
I have submitted Bug 86211 - Boot failure: Bad RIP value for rtl8192ce
for this issue.
Thanks,
