Can I get the following questions answered by the people who have been seeing this problem?
Does it occur with FBC disabled?
Does it occur on the builtin LCD panel?
Does it occur when only one display is attached (builtin panel or otherwise)?
At this point, I suspect the memory arbitration or FIFO settings may be incorrect in some cases, and FBC exacerbates the problem (but it still might happen in other, non-FBC configs).
I updated the register dumper in git master so that it will dump the FIFO watermark regs, I'd appreciate register dumps from problem configurations.
In the meantime, I'm trying to reproduce locally by abusing my memory arbitration & FIFO watermark regs...
