Description Dan Raymond 2014-12-01 02:46:35 UTC
I am using a Raspberry Pi B+ and I am booting from an SD card using a clean image that has /usr/ports preinstalled.  Next I run "portsnap fetch update" and it panics around 20 minutes into the operation.

I have tried two different Raspberry Pi B+ units.
I have tried three different USB power cables.
I have tried four different SD cards (Transcend 16GB Class 10, SanDisk 32GB Class 10, Samsung 32GB Class 6, Kingston 16GB Class 4).

The panic is reproducible regardless of the hardware combination.

This build is otherwise fairly stable (if I don't perform "portsnap fetch update") depending on the SD card I use.  With the Transcend and Samsung cards I have been able to build various ports for over 24 hours without a panic.  However, I did see a panic with the Transcend card after 10 days of heavy use during an interactive SSH session.  When that happened I could no longer boot until I reimaged the SD card.  Not sure if this is related.

As of r277334 this panic is no longer reproducible.
