I have posted a bug report on quite a similar issue with the SD-card
reader of the Acer Aspire V5-131 (same Broadcom chip).
It is available here:

** Description changed:
I have a Broadcom BCM57765/57785 SDXC/MMC Card Reader internally in my
MacBook Pro Retina 13", and it does not work.
WORKAROUND:
- 1. Add the following to /etc/modprobe.d/sdhci: options sdhci debug_quirks2=4
- 2. Re-generate initrd: sudo update-initramfs -u -k
The mail was plaintext all along. It also seems that they discard too
large mails. I trimmed it down to 51KB by removing lots of less relevant
log data.

Magnus Hoff, vger.kernel.org silently discards html encoded e-mails. If
you didn't explicitly set your e-mail to send things as plain text, then
that would be why it didn't show up.

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 :)

Magnus Hoff, if the problem is reproducible with the latest mainline
kernel via http://kernel.ubuntu.com/~kernel-
ppa/mainline/v3.15-rc6-utopic/ , then the issue you are reporting would
be an upstream one. In this case, could you please report this problem
through the appropriate channel by followi
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 an

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 :)

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
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

The result is that I am successfully able to mount and use my SD card,
hooray!

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.
