I am experiencing the same problem on my 13 retina MacBook Pro
(MacBookPro10,2). I have discovered that things work better when using
the b43 module instead of wl to drive the wireless:
sudo rmmod wl ; sudo modprobe b43
However, this workaround makes the 5GHz networks disappear from my list.

No, it's not supposed to be there by default. Just create a new file :)

I created the report as specified and sent it to linux-

You have understood correctly. The mentioned patch did not change
anything, whether or not I engaged the workaround.
That said, to my eyes, the patch looks like it might be related. There
are some mentions of broadcom quirks and UHS mode in there. But the
bottom line is that I didn't experience
Sure, I'm on it. It looks like I will have to allocate some time for it
later, though.
Thanks for helping me out with how to do the reporting :)

I wasn't very clear: The mentioned kernel patch is a red herring, it did
not cause the changes I observed. I am currently using the stock ubuntu
kernel (3.13.0-24-generic) with the kernel module parameter, and the
workaround works :)

I have a Broadcom BCM57765/57785
I have now applied the patch found here:

next/+/fd1acc54a6b3db4e6503ccc4a9349f28b436031a
The result is that I am successfully able to mount and use my SD card,
hooray!
dmesg output looks like this:

Ah, I was cheering prematurely, sorry.
It seems that the mentioned patch did not effect the observed change in
behavior, so presumably something has changed in the stock Ubuntu kernel
to do this.
The currently observed behavior with stock ubuntu (3.13.0-24-generic) as
well as my patched kernel
Well. I've now added options sdhci debug_quirks2=4 to modprobe.d, and
this seems to make it treat the card as high speed rather than ultra
high speed, which works, although at a poorer speed than theoretically
possible.
I can attach and detach the card multiple times, and sleeping and waking

I have tested with 3.15.0-031500rc1, as requested and it did not fix the
problem. It did not change user observed behaviour either.
However, it *did* change stuff that appears in dmesg.
