This is on a new raspberry pi from element14 (SD card also from element14). Only changes have been a dist-upgrade. Extract fro dmesg:-

[ 1.261911] Waiting for root device /dev/mmcblk0p2...
[ 1.335949] mmc0: problem reading SD Status register.
[ 1.338761] mmc0: error -84 whilst initialising SD card
[ 1.437154] mmc0: problem reading SD Status register.
[ 1.440229] Indeed it is in host mode hprt0 = 00021501
[ 1.449582] mmc0: error -84 whilst initialising SD card
[ 1.559803] mmc0: problem reading SD Status register.
[ 1.563112] mmc0: error -84 whilst initialising SD card
[ 1.639595] usb 1-1: new high-speed USB device number 2 using dwc_otg
[ 1.639767] Indeed it is in host mode hprt0 = 00001101
[ 1.716980] mmc0: new high speed SDHC card at address 59b4
[ 1.717629] mmcblk0: mmc0:59b4 00000 3.67 GiB
[ 1.719247] mmcblk0: p1 p2

The raspberry then continues to boot up with no problems.

@hvenzke

Upgrade your kernel to 3.8.4 i.e shuold solve the issue as it contains some more SDHC dwc_otg patches.
My of SHDC/ SHDX 16-64G cards runs fine with that :

apt-get install git-core
sudo wget http://goo.gl/1BOfJ -O /usr/bin/rpi-update && sudo chmod +x /usr/bin/rpi-update
sudo rpi-update 2c4e92c01ff14d8f3e1ee35b995d430b4e6d1e1b

NOTE : This seems an Pre-release (TEST) Firmware and may able to contain unfinished code - be warned - use on your own risk.

see https://github.com/Hexxeh/rpi-firmware, https://github.com/Hexxeh/rpi-update as reverence

@nmaas87

@remsnet Is this checkout still the latest pre-release firmware, or is there any "new" version including all these patches? Thanks a lot!
