I'm seeing strange issues on the Raspberry Pi B2.

- On all B2s
- But not on A+s or B+s
- On all of my Samsung EVO 16GB sdcards
- But not on sdcards of other brands
- And not on my 32GB EVO sdcard
- Randomly (only reproducible 50% of the time)
- Is non fatal (just cycle power, and 50% chance it'll boot normally. If not, try again)
- Leads to permanent corruption (eventually the sdcards are left unmountable)
Steps to reproduce
- Download the latest Raspbian
- Burn to EVO sdcard with
Win32 Disk Imager
- Put in card and apply 5V power (w/ 2.4A PSU)
- Pi may very well crash on first boot.
What I know
- This person seems to be having the same issue (with details)
- People here seem to be having mixed results with EVO cards (but details are scarce)
The error mentions
bcm2835, but the B2 runs a
bcm2836. Idk. Maybe they share MMC code? I wouldn't be surprised.
I know the following about the cards:
pi@isengard ~ $ cd /sys/class/mmc_host/mmc?/mmc?:* pi@isengard /sys/class/mmc_host/mmc0/mmc0:59b4 $ echo "man:$(cat manfid) oem:$(cat oemid) name:$(cat name) hwrev:$(cat hwrev) fwrev:$(cat fwrev)" man:0x00001b oem:0x534d name:00000 hwrev:0x1 fwrev:0x0
Normally, I'd just switch to a different sdcard and move on with my life, but this is for a very large project (>200pis). I'd very much like to know what's going on, if it's fixable, and if I should start moving the project over to new hardware. If you can't help, consider an upvote. The rep will go towards a bounty.
