Oopses from wireless device in F19

I just recently installed F19 on a new Dell Inspiron R15 7537 and since
then I've been getting kernel oopses from the wireless device.  What's
interesting :-( is that right before the oops if I do

cat /proc/sys/kernel/tainted

it returns 0.  Right after the oops it returns 512.

I have no extra kernel modules installed.  So I don't understand why it
suddenly shows my kernel as tainted.  This oops happens at least once per
day, and sometimes more.  The only way to get the wireless working is to
reboot.  Also the network-manager applet still shows me as connected even
though I can't ping out to the internet.  If I try to disconnect the
wireless and retry it never reconnects until I reboot the laptop.

Anyone else seen this behavior?

Any assistance is appreciated.

I submitted a bug via the abort applet, but I can't find the number.
