Raspberry PI 2 not booting after update

[dipogon]

Hi,
I copied a sd card image from an old card to a new sd card with dd. New card is Transcend Premium 300x UHS-1 32GB. Everything was working ok (booting, rebooting, running some time) but after updating with pacman -Suy today (at least firmware and kernel were updated) RasPi2 won't boot, says something like "mmcblk0: error -110 fetching data..." and "I/O error". Same error message repeats over and over again. I can mount the partitions ok in my desktop computer. Tried copying and update twice, same result.

Anyone else experienced this? Any ideas what could cause this?

The Pi's MMC controller probably can't properly talk to your card.

Hi,

exactly the same error after updating firmware and/or kernel with pacman. stock at boot with mmc error!

Same issue as well over here. My server appeared to be down this morning when my mother started complaining the internet was broken. Presume it was the kernel since everything was working fine until it hit it's reboot time.

Issue lays in the kernel (4.1.15-1).
Downgrading the kernel to 4.1.13-1 solves the issue.

We need an actual log.

Also, what models, and what model of SD card.

No booting issues here after update (which incl linux-raspberrypi 4.1.15)... only had to downgrade tinyxml due to kodi errors.

I have the same problem with my RPi2. I use Lexar 633x 32GB. I have no idea how to extract logs without logging in but I have a semi readable picture here http://imgur.com/eXL3yn0. Hope it helps.

Also how do I downgrade the kernel when I can't even access the system?

Same bug with Raspberry Pi 2 and Transcend microSDHC UHS-I 16GB (model TS16GUSDU1) after upgrading.

The kernel writes lots of mmcblk0 read error messages to console and finally:
$this->bbcode_second_pass_code('', '
kernel BUG at drivers/mmc/host/bcm2835-sdhost.c:900!
Internal error: Oops - BUG: 0 [#1] SMP ARM
')
- see screenshot at http://i.imgsafe.org/cf38203.jpg (sorry, I don't have an adapter to connect to RPi's serial console, so I just used a digital camera).
