"Fatal kernel mode data abort" every 2-3 boots on Raspberry Pi B+

Hi!

I'm experiencing a strange issue. I'm running a Raspberry Pi B+ with a Transcent 8 GB SD card. I'm getting the attached screen every two-three reboots. I'm not really sure what's the problem.

Thanks!

Sometimes I have this fault too, but it only begins with
Code:
Fatal kernel mode data abort: Translation Fault (P)
I don't have "Register Dump". I plug the SD card into my laptop, run fsck_ufs on the UFS partition, and it works fine.
 
Same story here, using EMTEC 8GB and 16 GB cards. I get the following about 50% of the time on boot-up. I'll get some different Micro SD cards and see if that makes a difference. May be several days before I can play with that.

Code:

I replaced the EMTEC Micro SD HC with a Sandisk Ultra PLUS microSDHC UHS-I card and I am not getting the VM faults any more. So far I have had 20 consecutive reboots without any problem. I have it set up to automatically reboot itself, and will let this run through the day, but I don't anticipate any further problems. Changing the card did the trick for me.

After 100 consecutive reboots without error I've declared victory. It's happy with the SanDisk card. Not sure why the EMTEC has problems, but I don't have the bandwidth to troubleshoot that now.
