I answered "never", though on average it freezes once every 4 weeks.

The freezes have all been some sort of I/O deadlock. traffic to and from OneNAND has worked, but both mmc have been completely stalled. Everything that wants to touch swap or /home freezes up, and sooner or later everything will be waiting on mmc. Not every occurence has left me iwth enough working processes that I've been able to figure out what's happened.


As for the person copying large files.. With swap, MyDocs and /opt on the same device, the emmc really slows down alot under heavy loads. Contrary to popular belief, seeks are not fast on emmc when it comes to writing. Random 4k writes, or writes interleaved with reads can cause some 32-64-fold slowdown of the emmc..
